Wpc.dll corruption after upgrade

[Guest]

I bought an HP a1730n with Vista Home Premium already installed. I purchased
the Vista Ultimate Upgrade and performed the upgrade. Now, whenever I try to
go to My Games, or run Hearts, or any of the games from the games menu, I get
this message:

Hearts.exe - Bad Image
"C:\Windows\System32\Wpc.dll is either not designed to run on Windows or it
contains an error. Try installing the program again using the original
installation media or contact your system administrator or the software
vendor for support."

I've gone to the Uninstall Programs - Turn on / off Windows Features, and
removed the Games, then re-installed them, but it didn't fix the issue. Is
there something else I can do?

With Vista Ultimate (in french version) I have the same problem.
