I too had this problem this morning. I probably had VS open as I'm lazy like that I guess. Never had an issue with it before, but found a fix online today.

"Hey guys, I too had this same issue, although I'm not sure what triggered it. Dependency Walker was telling me that dwmapi was missing (i'm running XP sp3) and getting that dll and putting in the lcoation it was telling me only made more errors. I finally found this thread, and started looking around the Windows directory and found that the atl90 dll was in fact missing in one of the four C:\WINDOWS\WinSxS\x86_Microsoft.VC90.ATL_ directories. "
So basically, find (hopefully) the atl90.dll file in one of the 4 C:\WINDOWS\WinSxS\x86_Microsoft.VC90.ATL_* directories and plop it into any of the remaining 4 that don't have it. That fixed it on my end anyway.
