This application has requested the runtime to terminate it in an unusual way please contact the application's support

I randomly get this error message "This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support." 

Here's a picture of it. http://i48.tinypic.com/35hradh.jpg  

It doesn't tell me what application or process is responsible. :/

It pops up randomly when I wait long enough. It will pop up even if I don't have anything open and I just leave my computer to idle. When I close it or click okay, windows explorer gui will crash and restart. I can still use the computer after this without restarting but again if I wait long enough it will occur again. I've look around and tried many solutions but nothing has worked.

I've tried a full virus scan, and malware scan with no luck. Tried the registry cleaner from CCleaner and doesn't fix it. I've ran it in safe mode and the error didn't seem to occur or maybe I didn't wait long enough (30-40 minutes).  I've tried a SFC scan and nothing comes up as wrong. I've done a cleanboot several times with no help. I can't do a system restore since the latest restore point is on the same day that I got the error unfortunately.

When the error occurs the pop up window is from Microsoft Visual C++. I've tried uninstalling and reinstalling Microsoft Visual C++ for my 2010 versions but with no luck. I've uninstalled the recent programs that I installed and no help either.

In the event viewer, it shows  that there is an error and the source is an application error. The details are...

I checked the process that the error message window links to and it is explorer.exe but I'm not sure what I can do since it's an essential windows file and I can't just delete it.

Anyone have any ideas what is going on?

Thanks.
