Hello folks, getting this message on startup:

The program can't start because MSVCR80.DLL is missing from your computer. Try reinstalling the program to fix this problem.

Apps causing this error: ATTCM.EXE. I did have this problem with ITunes and Quicktime, also.

I have tried to uninstall and reinstall the apps that are causing this problem, but it keeps coming back. I have tried several things I found concerning Quicktime and Itunes, but no luck.

I have tried Windows 7 boot repair also.

Any ideas?
