Runtime error r6034 microsoft visual c++ runtime library explorer.exe
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.
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.
