In that case, I cannot explain the behaviour you are seeing nor am I able to replicate it. Feel free to use the "Email Blog Author" button above if you would like to share the package with me to see if I can find anything.Anonymous

Gautam, can you check you can replicate this with SP2 please. Arokiyaraj, 1. If you package is entirely VFS then non-admins won't have access as described in this post. 2. Please can you upgrade to SP2 and check that this is still an issue please.Anonymous

Hi Arokiyaraj, this is not a scenario I have tested and would need to be done on a package basisAnonymous

Hi Dan, thanks for sharing your blog post, the team are aware that the ability to modify permissions in the VE is highly desired with App-V 5.0. Sequencing to the PVAD or specifying it as the place you would like to be writable is one technique you may employ, although this isn't ideal for apps that have multiple locations. App-V 5.0 is really just keeping the default security of the folders that are outside of the package root but I do agree this does not give us as much flexibility as we had in previous versions.Anonymous

Hi Paul, Thanks for sharing!Anonymous

The thing to understand is the article relates to permissions the user has when running the application not the ability for a user to directly go and modify those locations outside of the application running in the VE. There is no documented or supported way to directly change either location you have specified, the cache holds a static state and is not writable, state changes are described in more detail here: blogs.technet.com/.../app-v-5-0-os-integration-part-4-state-changes.aspx This article describes what state changes are permitted across VFS and PVAD for non-admin and admin.Anonymous

VFS directory have two other directories i.e; ProgramFilesCommonX86 , windows . I didn't alter permission , we are working with default permission only.Anonymous

Ah okay great. Is the VFS directory a user profile based location? If not, have you changed the default permissions on the root of the place where the VFS folder resides?Anonymous

Okay, further to our messages via email it looks like you have non-default permissions set on these directories as you can write to these places natively as a non-admin user. I'll explain what you are seeing in a post very soon.Anonymous

First can you please clarify, in what context you are trying to make changes? Are you physically browsing to the cache location and trying to change files or are you running an App-V package that writes to these locations?Anonymous

I installed the package and then launces shortcuts , then navigated File--->Open---> and reached to PVAD(root) and VFS location in VE and tried to create new folder in Root directory and in VFS directory as Admin and as Non Admin and in both cases , i was able to write.Anonymous

Thank you for your response Thamim As per above mentioned contents "PVAD has write access to both admin and non-admin and the VFS only gives write access to admin." but when i checked , i found that both admin and non-admin have write access to PVAD , VFS in "C:ProgramdataAPPV............" on Client. Can you please let me know your thought on this?Anonymous

It's a shame that there's no way to open up these permissions - there will be plenty of badly written legacy applications that depend on quote access to certain locations. With Windows Installer we could set permissions on install, with App-V 4 we could change permissions during sequencing and they would be captured, or we could disable security descriptors entirely... With App-V 5 it seems the only option we have is to use shims. I hope that Microsoft take notice and provide a way to really alter permissions in a future update. Until then, I have my own workaround! packageology.com/.../file-permissions-app-v-5Anonymous

Whatever descibed above , I tried to implement the same as an admin and non-admin and found was not positive. Please let me know, whether we could write or not as an admin or user in C:ProgramDataApp-V71A57C9A-3E3F-4308-B8E1-3909096F02E6C549E4AE-DEF3-4BD1-83EB-59639F648F44Root and C:ProgramDataApp-V71A57C9A-3E3F-4308-B8E1-3909096F02E6C549E4AE-DEF3-4BD1-83EB-59639F648F44RootVFS or C:UsersABCDAppDataLocalMicrosoftAppVClientIntegration7532754F-9420-4D4E-B0F5-D55E94EB67EARoot and C:UsersGautamAppDataLocalMicrosoftAppVClientIntegration7532754F-9420-4D4E-B0F5-D55E94EB67EARootVFS Please give brief descriptions based on above directory structure.Anonymous

Hmmmm I am assigning my PVAD during sequencing as the install directory but when I deploy my app, users are presented with an error cannot find C:MyappMyapp (which I specified as the PVAD). When trying to browse to this location by typing it in manually (as I know it is hidden) it says that it doesn't exist. Am I missing something?Anonymous

Here is a solid solution for the C:ProgramData allowing write permissions for everyone Full. But I am unable to get write access to the C:UsersadminAppdataLocalMicrosoftAppVClientVFS"GUID"Common Appdata, now that being said, once the application is launched I can go in and manually add permissions which has resolved the issue for me 100% of the time, but I cannot do that for every user, ugh. Need help on that one. Here is the cure C:ProgramData.... Permissions Within the DeploymentConfig.xml file locate the Machine scripts, take out the "Comments" <!-- and --> and the following lines. <MachineScripts> <AddPackage> <Path>cmd.exe</Path> <Arguments> /c %SYSTEMROOT%System32icacls.exe "[{AppVPackageRoot}]VFSCommon AppData" /grant Everyone:(OI)(CI)F </Arguments> <Wait RollbackOnError="true" Timeout="30"/> </AddPackage> </MachineScripts> PaulAnonymous

I meant add the following lines :-) PaulAnonymous

You can do that by running it as a userscript instead. then change acl by removing the folder and adding it again, then the security will be opened.Anonymous

Thamim -- I have couple of questions to be answered.. 1. I have a 5.0 converted package where in after install the application is unable to write or modify files to its own folder and reporting as access denied. Is there any ways that it can be fixed. 2. For some 5/0 converted applications, even DLL files are present inside the bubble where it was in 4.6 package but still upon shortcut launch it throws that file is missing, any reason for this and anyways to fix this.Anonymous

Hi Thamim - Thank you so much for your suggestion. I do have a straight General question. So any applications which are converted from 4.6 to 5.0 will have VFS folder structure ?, If so NON-ADMINS will not have access to modify something on that manually. But Is this same applicable to the application it self to modify certain files during runtime on the Standard users environment. ThanksAnonymous

Hi Thamim, Please can I get some on info on the above asked questions. Thanks.
