New Post: Strange error with Win2012 R2

I'm encountering an error 0x80070643 / 0x80131700 with a package I've rolled out, which tries to unregister VGX.DLL. It worked on XP and Win7 (and 2003 and 2008), but not 2012. I'm not sure if it's some kind of bug or some permissions setting that I'm missing. Also there was no WPP log file created in C:\Windows\Temp.

Here's the log from one of our servers:
