Hi!
I encountered a problem with my Windows 7 SP1 Professional x64 computer. Problem started two weeks ago after I installed the monthly Windows updates. After the updates every time I restart or login to my computer I get the error message saying "Runtime error r6034 microsoft visual c++ runtime library C:\windows\explorer.exe". After I hit "ok" in the error screen I can use Windows normally. I also get the same message when I try to use Explorer in different programs, for example notepad. Only difference is that now the path in the error refers to notepad. And again, I can still pick a file to be opened after I press ok in the error screen.
Problem occurs also in Safe mode and clean boot didn't help either. I also tried system restore to a previous configuration with similar results. I re-installed Visual C++ Library 2010, but it didn't help. I tried to install every single Visual library version (both x86 and x64 ) from 2005 to 2012 without success. Event log shows no errors so no help from there.
Can you give me any advice, what to try next?
Locked Question. This question was migrated from the Microsoft Support Community. You can vote on whether it's helpful, but you can't add comments or replies or follow the question.
Here's a simple solution which worked for me: I right-clicked on the offending program, selected "Properties," clicked on the "Compatibility" tab, in the "Privilege Level" section, I checked the box for "Run this program as an administrator", then clicked the "Apply" button. Presto. Problem solved. I have no idea why this worked, and I don't want to hurt my brain trying to figure that out.
I found the guilty for the problem, which was my backup software. I informed the software developer about this and they said that the problem will be repaired in the next patch.
Totally agree. Whoa is this frustrating. Using Windows 7, I uninstalled and reinstalled iTunes, all allowable Apple Products, Microsoft Visual C, ran a full security scan, etc. and continue to get the Runtime error 6034 with iTunes and when booting my computer. This renders iTunes useless. I'm not very techie and would very much appreciate some direction and help getting this resolve. Eeeeek!
I just ran into this problem and I followed iTunes suggestion to update/repair my .Net framework. I did that and I still get the stupid error! I am so furious that I even attempted to update iTunes... anyone know how to fix it? I can't even open iTunes!
Can you please tell us exactly what backup software you were using? That would be very helpful, for sure. I am surprised it wasn't included in your message. Thank you so much!
