    Hi Gody - I have not posted a blog item about error code 25015 yet because we have not narrowed down any definitive root causes of that error yet.

    Can you please try to use the manual removal steps for the .NET Framework 2.0 that are listed at http://blogs.msdn.com/astebner/archive/2005/04/16/408856.aspx and then try to re-install the .NET Framework 2.0 and see if that resolves this issue?  If that doesn't help, I would suggest contacting Microsoft technical support (you are entitled to a free support call for .NET Framework setup issues).  I'm sorry I'm not able to be more helpful here.

    Hi Aaron!

    I work at Intuit where I support Quicken Medical Expense Manager, which installs on top of .NET Framework 1.1. I have been working with your .NET Framework team in Bangalor, specifically with Arun Ramalingam and Aditya Hari (mostly) and they have been UNBELIEVABLY helpful in helping me to get my customers fixed when we discover that their .NET Framework is broken. They shared your cleanup tool with me and it has cut my support call time from 2 hrs to 20 min. Many KUDOS to you for developing it! Everyone that I have spoken with at Microsoft has been so kind and helpful and I intend to write a note to Bill Gates to let him know what a great team of folks that he has!

    I have one last question for you, can you explain to me, in laymen's terms, how and why the .NET Framework can break? I just want to understand a bit more so that I can attempt to explain it to my customers when they ask.

    Thanks so much!

    Hi Megawatt - Thank you very much for this feedback on Arun and Aditya as well as the .NET Framework cleanup tools.  I have passed this feedback on to the technical support managers that oversee the .NET Framework products as well.

    Your question about how/why the .NET Framework can break is not a simple one to answer.  Like any reasonably complex piece of software, there are a lot of possible points of failure.  The .NET Framework relies upon the presence of many files and registry keys, so if any of them are missing, have bad data, have incorrect versions or are corrupt, it can lead to unpredictable results.

    Since the .NET Framework is a runtime that other applications use, when it is broken, it can lead to unpredictable results and crashes in those applications.

    The most common cause of fragility in the .NET Framework that I've seen in my past experience is related to the file %windir%system32mscoree.dll.  That file is a shim that is shared by all versions of the .NET Framework, and it enables side-by-side functionality by determining which version of the .NET Framework to use when running any given .NET application.  If that file is corrupt or somehow gets downgraded, it can cause applications to fail to load.  As a general rule of thumb, that file should be versioned the same as the highest version of the .NET Framework you have installed.  For example, if you have version 1.0 and 1.1 of the .NET Framework on your system, that file should be versioned 1.1.4322.

    Hope this helps.  If you have any more specific questions that I can help you answer for your customers, or if you run into any further problems, please don't hesitate to contact me.

    Hello, Aaron;

    First, thanks for the wealth of information you've poured out here.  However, I've spent the better part of a day trying to reinstall .NET Framework 2.0, and I'm just stumped!  First, I tried it through Windows Update, but that gave an error code (0x643).  Then, poking around here, I learned about dotnetfx.exe, downloaded it, and attempted to install it.  However, each attempt ended with the message:

    Error 25015.Failed to install assembly
    'C:WINNTMicrosoft.NETFrameworkv2.0.50727System.dll' because of system
    error:
    The system cannot find the file specified

    Where is system.dll that the system can't find it?  Should it be placed in the v2.0.50727 folder as part of installation?  A search of my system shows there is no system.dll.

    I've already used the clean-tool and performed the manual clean up.

    I realize this may not be the appropriate forum, but I'm desperate!  Any help would be appreciated.

    Thanks!

    Dennis

    Hi Gormboy - Just to confirm, you've already tried to run the tool described at http://blogs.msdn.com/astebner/archive/2006/05/30/611355.aspx and that didn't help, correct?  If not can you please try that.  If so, can you please try to us the SubInAcl tool described at http://blogs.msdn.com/astebner/archive/2005/08/09/449720.aspx to try to fix any permission issues that might exist on your system?

    If neither of those help, your best bet is to contact Microsoft technical support for further troubleshooting assistance.  There is contact information at http://support.microsoft.com/?LN=en-us&scid=gp%3Ben-us%3Bofferprophone&x=15&y=12.  That site says that you have to pay, but for setup-related problems such as this, there is not a support charge.

    I am getting "1603:error installing .Net framework" on installing .NET 1.1 on Vista. Can you please help?

  • Anonymous
    June 20, 2007
    Hi Soniavdas - Error code 1603 is a generic failure code for an installer.  You will need to gather a verbose log file from the failing setup to be able to narrow this down further.  You can use instructions like the ones at http://blogs.msdn.com/astebner/archive/2005/03/29/help-me-help-you-if-you-have-setup-bugs.aspx to do this.  If you can gather this log, zip and send it to me at Aaron.Stebner (at) microsoft (dot) com, I will try to take a look and see if I can figure out any possible causes of this issue on your system.

    Hi Takuboku - From what I can tell in the verification results, the .NET Framework 2.0 should be correctly installed on your system.  The language mismatch for that one file and the higher versions for those other 2 files are OK to ignore in this case. If you are still getting a .NET Framework 2.0 installation error from SQL Server setup, there may be something strange in the logic that SQL is using to detect the .NET Framework.  If that is the case, I'd suggest posting a question on the SQL setup forum at http://forums.microsoft.com/MSDN/ShowForum.aspx?ForumID=95&SiteID=1 and hopefully someone there will be able to suggest a fix for you.

    Hi Fabien G - The only instances of this issue that I have heard of in the past were caused by having leftover pieces of an old VS 2005 beta somewhere on the system.  In some of those cases, running the VS 2005 beta cleanup tool at http://astebner.sts.winisp.net/Tools/vs2005_beta_cleanup_tool.zip might help. If that does not help on your system, then I'm not sure what other workarounds to suggest.  It might help to post a question on one of the MSDN forums (http://forums.microsoft.com) to see if someone there has any additional ideas. I'm sorry I'm not able to be more helpful in this scenario.

    Hi astebner, thanks for your help, but the cleanup tool didn't solve the issue. I feel that my computer is corrupted, but I don't know how to inspect it. I asked a collegue to look at it, but we'll probably have to reinstall the computer if we don't find any other solution :( Thanks

    Hello Aaron, I have problem installing SQl Server 2005 under laptop's Windows XP SP2 with the same error every time: "Setup detected a problem with .Net Framwork instsallation and cannot proceed. Microsoft .Net Framework 2.0 is either not installed or is corrupt". I have .Net Framework 2.0 install file which I downloaded directly from Microsoft. I reinstalled .Net Framework 2.0 few times. First, I removed thru Control Panel. Then for removal I used Windows Cleanup Tool. Then I used your manual removal steps. In addition, I used your Framework verification tool which shows success. But error persists. Did I used everything I could for repair? Regards Vladimir Kievsky

    I am curious does anybody else has the problem of automated registration for installation of Windows updates. With my XP installation I prefer to review and choose the desired updates, disabling some. Several months ago though I was surprised to see that I have pending updates on my shutdown option with no other means of reviewing them. Since I do a lot modifications to my Windows with software installs and updates, I suggested that I have done something wrong, although I could not remember what. Now I made a brand new installation with a sp3 integrated install and everything was fine till the moment I installed .NET FX 3, shortly after that I had to restart and I saw that there are new updates in the shutdown option. I was frustrated and immediately went for a System Restore, which eventually helped and now notification of updates is back. Still I need to install again that NET FX 3, because of software dependencies Have anyone seen such behavior and what do you do to review and modify the list of pending updates?

    Hi Garny - It sounds like your system is configured to automatically download and install updates when you reboot your system.  There is a knowledge base article at http://support.microsoft.com/kb/306525 that describes how to change automatic update options on Windows XP.  I'd suggest reviewing that article to see if they can help you configure different automatic update settings that are closer to how you want your system to behave.

    I is curious that the verbose log only shows Error 25015 if there is no .NET Framework installed at all - no version installed. If V. 1.1 is installed, and I try to install 2.0 over it, the same Error 25015 occurs, but it doesn't show in the log.

    Hi Snappletooth - I have seen error 25015 before, but there are a lot of possible causes, and I haven't seen that exact error message (the volume does not contain a recognized file system) happening during .NET Framework setup before.  I'd suggest first trying the steps listed at http://blogs.msdn.com/astebner/archive/2008/03/07/8108332.aspx to see if they help at all here.  If those steps don't help, then the MsConfig tool listed at http://blogs.msdn.com/astebner/archive/2006/11/25/disabling-services-with-msconfig-to-work-around-setup-failures.aspx might also help.

    Hey Aaron, I have tried to install the Visual Studio 2008 SP1, but it freezes when it gets to the .NET Framework 3.5 SP1.  I then tried to install the .NET Framework 3.5 SP1 by itself and it also just never completes. I don't get any error message, it just sits there running. I left it going overnight and it was still going 12 hours later, not actually doing anything though. The status bar is almost at the end when it stops doing anything. Any ideas?

    Hi Liam-davison - I'd suggest looking at the .NET Framework 3.5 SP1 setup log files to see what the last action it tried to do was before it started hanging.  You can find a list of the log files created by this setup at http://blogs.msdn.com/astebner/archive/2008/04/30/8445569.aspx. If you'd like, I can try to take a look and see if I can spot anything in your logs.  To do that, can you please zip your logs, upload them to a file server of your choice (such as http://skydrive.live.com) and then post a comment back here with a link to the location that the log files can be downloaded from?

    I had all sorts of problems trying to install .NET 3.0 and I've read just about everything on this website and tried most of the fixes...There was a fix mentioned in the .NET 3.0 readme where IIS prevents .NET 3.0 installation. I removed IIS 6, then all my problems went away and install was fine after that...I will re-install IIS 6 later. All the logs seemed very misleading.

    Mr. Stebner,  Your blog is awexome! I beg your pardon for asking such a low-level newbie question as this, but I also cannot get the recent patches for .NET Framework 1.1 and the other one for 2.0 to install. I have little more than NO idea of what these things are doing for me, in my system. I am not running this machine as a server, and it is not in a domain, just a standalone desktop with DSL internet connectivity (att.net)  The two recent Windows Update critical patches for .NET Framework v 1.1 failed with error code 0x645 and for v2.0 wit error code 0x64C. Not 0x643, the 0x643 is covered thoroughly. So, here's my simpleton question:   Which versions of .NET Framework are needed on my WinXP SP3 machine? Info: My Add or Remove Programs lists the following: Microsoft .NET Framework 1.1 Microsoft .NET Framework 1.1  Hotfix (KB928366) Microsoft .NET Framework 1.0  Hotfix (KB928367) Microsoft .NET Framework 2.0 Service Pack 2 - and ten (10) indented items under this. Do you need to see this list? Microsoft .NET Framework 3.0 Service Pack 2 - and eleven (11) indented items under this. (List?) Microsoft .NET Framework 3.5 SP1   -  and two (2) Hotfixes. Is any one more than the latest (v3.5)  needed? Maybe the 3.5 rolls up the old 1.0 through 3.0??  Do I need to be updating all of these when an update is offered for each ? Do I need to install the .NET Framework 4.0?     Please advise.   FYI - This system:  HP Pavilion a1040n OS: Windows XP Professional SP3 32b regularly patched by Win Update except when it fails to install... CPU: Intel P4 519J 3.065GHz RAM: 2GB DDR 3200 HD: 148 GB free on system partition AV: Avast! updated typically every day AS: Windows Defender updated every two to six days since Oct. '08. FRWL: Windows Firewall enabled at present.

    Hi Falling Rock - What I'd suggest doing here is using the steps listed at http://blogs.msdn.com/astebner/archive/2009/10/23/9912209.aspx to remove the versions of the .NET Framework that are installed on your system and then try to re-install the .NET Framework 3.5 SP1 first (this will also install the .NET Framework 2.0 SP2 and 3.0 SP2 behind the scenes). You don't necessarily need to install other versions of the .NET Framework unless you have programs that you use on your system that require them.  I described this scenario in more detail at http://blogs.msdn.com/astebner/archive/2009/04/20/9557946.aspx, so I'd suggest looking at that to help you decide which version(s) of the .NET Framework to install on your system. I would suggest not installing the .NET Framework 4 for now because it is still in beta.  The final version will release early in 2010, so if you plan to install that version, I'd suggest waiting until then.

    For several weeks now my windows update has been failing on the .net 3.5 sp1 update.  Most recently I purchased TurboTax and it won't install without this update. I've tried several of the suggestions and tools on your blog with no avail. I'm running 32-bit Vista.  The setup verifier tool fails every time i try to run it with an error.  I tried running the cleanup tool. Then disabling all non-MS services on startup.  Reboot.  Then running the full 3.5 sp1 install.  It fails every time.  I'm at a loss as to what this issue could be.  Please help! Thanks!

    Just a little further info. When I run Belarc Advisor it reports the following two MS hotfixes as missing? KB979909 - Important KB983583 - Critical

    Hi Peking97 - I'm not sure how to explain the behavior that you're seeing in this scenario.  Sometimes, the Windows Update scanning logic will use cached data and continue to offer you updates that are actually already installed.  In those cases, it can help to reboot and try to run a Windows Update scan again after the reboot.  It might also help to try steps like the ones in the knowledge base article at support.microsoft.com/.../971058 to reset Windows Update on your system. I'm not familiar with the Belarc Advisor product, so I'm not sure what it is doing to determine whether or not those updates are installed.  It might help to remove those updates using the control panel and then try to let Windows Update install them again.

    All appears back to normal now after I un-installed and re-installed all the .NET installations. Belarc Advisor now reports all OK. I find it strange that the verification tool should report all OK whereas Belarc correctly identified those two as missing/corrupt. Anyway, as I say, all OK now. Thanks for the input and best regards.

    Hi I have a clickonce deployed application in my machine. When I tried to load the application, 90% of the application window is getting loaded but finally, I get the following error: Could not load file or assembly '0 bytes loaded from System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. An attempt was made to load a program with an incorrect format. I have read somewhere that this error could be caused when something goes wrong with the .net framework in the machine. My machine is having .Net framework 1.1, 2.0 and 3.0. So which framework should I reinstall? The application is developed using .net 2.0. Also, please let me know how the application is partially loading(90%) if the framework is corrupted.? Regards Anoop.

    Hi Anoop - This type of error could be caused by the .NET Framework being in a bad state on your computer.  I'd suggest trying to install the .NET Framework 3.5 SP1 (which will install the .NET Framework 2.0 SP2 and 3.0 SP2 behind the scenes) to see if that helps resolve this error.  If that doesn't help, then I'd suggest posting a question on the ClickOnce forum at social.msdn.microsoft.com/.../threads to see if someone there can suggest some additional troubleshooting steps for you to try in this scenario.

    Hi Michelle - This looks like a problem with a Toshiba registration program as opposed to a problem with the .NET Framework.  I'd suggest trying to contact Toshiba to see if there are any known issue with this program or any troubleshooting steps that that can suggest to solve this type of error.

    After wandering through this and any number of other sites dealing with .NET 3.5 install problems I found a solution that may be unique or may be helpful to others. Give it a try before you go completely bald: Uninstall MSXML 6.0 SP2 then try the .NET 3.5 SP1 install. Worked for me. If it works for you send me a gazillion dollars...or give $25 to your favorite charity. --Tinker

    Just thought I'd post this solution to my problem that has taken me 2.5 days!! I could not install .net 3.5 as it was crashing when trying to install .net 2 I was getting: error 25015 failed to install assembly system.messaging in the log was a message: warning: cannot obtain mscoree.dll version at c:windowssystem32mscoree.dll" and crashes involving: visualstudio8setup (even though this wasnt installed anymore) Tried .net cleanup tool, asl resetting tool, etc was at the end of my tether, thinking about a fresh install of windows XP, then I did this and it worked: rename C:WINDOWSassembly to C:WINDOWSoldassembly Warning, this is a bit drastic: I wouldn't be surprised if that broke any .net apps you have so you would have to reinstall etc.

    Hi Stan Lee - That's strange.  Normally, uninstalling + re-installing the .NET Framework 4 should solve this type of error.  I'd suggest trying to use the steps listed at blogs.msdn.com/.../8108332.aspx to fully uninstall all versions of the .NET Framework from your computer, then re-install the .NET Framework 4 Full and see if that will help solve this error. Also, what version of Windows are you running?

    Hi Stan Kremp - This is strange.  From what I know, TurboTax uses the .NET Framework 3.5 SP1, and the .NET Framework 4 should not interfere with the .NET Framework 3.5 SP1 at all.  I haven't been able to get the link to your log files to work, but what I'd suggest to start with is to use the tool and the steps listed at blogs.msdn.com/.../8108332.aspx to fully remove the versions of the .NET Framework that are installed on your computer, then re-install the .NET Framework 3.5 SP1 and the .NET Framework 4.  Hopefully doing this will restore your ability to use TurboTax, and also it will hopefully resolve the Windows Update issues you were seeing.

    I downloaded .NET 2.0 SP2 off of the Microsoft Website, and while extracting it says that "File is corrupt" and the file being extracted is "SitSetup.dll". When I try to manually extract the files with programs like Winzip and WinRAR, many of the files fail to extract. Do I need to download the file again?

    Hi BoxCoxGuy - For the .NET Framework 4, uninstalling the base product should also remove the updates.  I don't believe you need to install the updates separately.  I'd suggest using the Programs and Features control panel to remove the .NET Framework 4, and only use the tools on my blog as a last resort in case the normal uninstall process fails.

    Hi, Aaron. I have a problem with .Net Framework, i m using Windows XP and i installed .Net Framework 3.5 and 4.0, everything was working fine, then i found some other related updates in the option software section in windows update. So i installed them and i got my PC running slow and choppy so i used the restoration point created before i installed the last update to return everything as it was. It worked partially, i got almost everything working fine again, but i got an error when i try to run an internet TV program that depends on .Net Framework, i got the system.IO File Not Found Exception asking for a .exe file of that program. What should i do now?, i still can undo the system restoration that i did if it is necessary or id there any application that can fix my problem? Please, i need your help to fix this.

    Thx Aaron, i had found that post before you posted it, i followed it to fix my issue. First, i tried reparing the .Net Framework versions (from 2.0 to 4.0), after reparing version 3.5, i got my problem solved. But i lost a plus that i gained after installing 4.0, and that was playing youtube videos smooth. After Adobe flashplayer released its 11.202.235 version, most of the old PCs have issues with playing net videos, but after installing .Net Framework 4.0, i got an improve in my youtube videos. So i uninstalled/reinstalled .net framework 4.0 (installed the critical updates from windows update for .net 4.0 as well) and got the videos running smooth again (not perfect but a lot better than before of intalling 4.0). Everything is working fine now, thx a lot for your posts and your blog.

It works fine but with some programs i got this error message : docs.google.com/.../edit Follow the link above to check the error message (it s pretty big so i couldn t post it here) I have the option to choose Continue or quit, i tried continue with one program and it worked, but i don t want to get this error message from time to time. I have .net framework 3.5 installed and the versions before that as well, i have my windows XP updated with all critical updates installed, i tried repairing framework 3.5 in the install/uninstall programs section to solve the problem but no luck. You know how i can fix this issue ?? Sorry for bother you again, but you are really good with this. Thx in advance.

    Hi Christian - The error in the link you posted looks like a problem with the application that you're using, not a problem with the .NET Framework itself.  My suggestion would be to contact the application manufacturer to see if they have any known issues and/or patches for that type of problem.

    Well, if that was the only program that give me that error message i would think the same, but for example i got a similar error message with my internet tv program (this program worked without any issue with my old HD using XP and same version of framework, i m using the same version of the program as well) i click in continue and all worked fine and i didnt get that menssage using that program again. So i have some questions : if i click continue every time that message appears i wont get anything wrong with my PC in the future?? And i was thinking to update .net framework from 3.5 to 4.0, should i do it or i need to fix this issue first??

    Hi Christian - If you're seeing the same error message from multiple programs and not just one, then it probably is something wrong with the .NET Framework.  Normally, I suggest removing and re-installing the .NET Framework to try to solve that type of problem, but you've already tried that so I don't expect you to get any different results by trying that again. You can skip the error message without causing any further problems, but that can get annoying over time. It might help to install the .NET Framework 4, so if you haven't yet, I'd suggest trying that too.

    Hi Marco - Exit code 0x240006 means that this update is already installed.  That is expected if you've already got that .msu file installed, and it isn't the cause of a .NET Framework setup failure. In order to narrow down the cause of your .NET Framework 4 setup failure, can you please use the tool described at blogs.msdn.com/.../6458047.aspx to collect all of your setup log files, upload the file named %temp%vslogs.cab that this tool will create to a file server (such as http://onedrive.live.com), and then reply back here and provide a link that I can use to download your log files and take a closer look?

    I thought Id chime in and let you guys know what ultimately solved my problem, since I havent seen that on any other blogs. Check your log files for something similar to "unable to write to key" next to an incomplete registry key location. You gotta look that key up on your registry, then go up one level (on my case the next level up was "CLSID"), right click on it and change the permisions. First you must take ownership of the key (and the keys below it - this is important!). Then add the user "NT SERVICETrustedInstaller" with full control. I also added "System" just to be sure, but it suffice with TrustedInstaller. Before you close this dialog, make sure to select the checkbox that will inherit this user permissions to all children keys. If you get an error when doing this, it means you didnt took ownership of all children first, so go back and do it and repeat. This will allow you to finishe your installation. Afterwards you might want to reset these settings to normal. NOTE: The first time I did this it didnt work, because apparently there are multiple copies of the CLSID branch on the registry. If it doesnt work the first time, find the next CLSID branch that contains the key mentioned on your log file. It worked for the on the second try. Good luck!!!!!!!

    Hi Marco - Thank you for posting about your experience.  I'm sorry I didn't have a chance to look at your logs in the meantime (I just got back from vacation and am catching up on my blog comments now). For others reading these comments in the future, Marco's solution is specific to his scenario.  It may or may not apply to your scenario.  To tell for sure, you'll need to look in the verbose .NET Framework setup log files and determine the exact cause of the failure, and then find a solution from there.
