XP SP3 causes weird things to happen.

[ExAm]

One thing I've found so far is that the UT3 demo will no longer open. It gives me a "modified executable code is not allowed. please reinstall the game" message. I haven't tampered with the file in any way, and reinstalling it doesn't help.
Anybody have any ideas?

I'm sure there's more stuff than this, and I hope it all gets fixed with the final release of SP3

Best solution would be going to a support page for UT3

Isn't SP3 still a release candidate?

Modified executable code...sounds like the want to avoid debuggers/crackers/reverse engineering guys. Why XP would modify the exe, I don't know.

SP3 is supposed to give noticeable speed boosts right? I'd imagine that means it handles programs in a different way, making UT3 angry.

Have you tried uninstalling SP3? It's in add/remove programs I think, but you'll have to ask it to show Windows Updates.

Any way to downgrade service packs?
