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

Question

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?

Answer 1

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.

Had this problem on a Vista PC when trying to download latest iTunes, pretty much as described by others.  After a couple of tries, I decided to uninstall iTunes, but the error stopped this too!  Best I could get out of Apple was that it's a Microsoft problem

• not entirely convinced.

I had Apple de-authorise my max. 5 PCs, including the one on which I cannot now run iTunes, and I am now re-authorising the remaining 4 plus another not previously included.

This is not, of course, a solution, so I attempted a restore back before the attempted iTunes download - sadly it failed!  ... and has continued so to do for several attempts.

Upshot is ... can't chance trying to re-download iTunes onto this PC.  NOR will I upgrade any other of my PC's to the recent new version, I case this happens again.

All of this suggests that, since it was the attempted download of new iTunes that caused (or maybe highlighted) this issue, maybe Apple SHOULD take a strong interest!

Well if it is like my case you will find it effects just about every thing you are going to try to do on that PC. Lots of programs use C++ and the only chance of fixing it is to try my suggest solution above of uninstalling the other Apple apps and then reinstalling iTunes. . If not convinced try searching all the threads on this subject on the Apple forums.  Good Luck.

Hi,

I am also getting error message R6034 when logging in, it seems to be effecting DVD RW in so much as the computer has lost is not reading any of my DVDs. Repair agent hung a new dvd in and it still did not work. Connecting a USB DVD RW does not work either. To be honest at 70 years of age I am not switched on to these problems. Can anybody help me to sort this problem.

I have the same problem and did a system restore to Jan 14th well before the problem arose, but that did not help either
