I´m starting to regret upgrading my computer to Win 7 seems all kinds of games won´t run in win 7 64 bit.

first it was Sacrifice and now Arx Fatalis the problem so far is that when ever i start the game up it will show the company logo and then it immediately minimizes like i pressed the windows key on my keyboard.

No matter how many times i press it it always happen and it won´t even stay up for a second before minimizing again.

Is there any way to fix this??

Have you tried running it as an administrator and under different compatibility modes?

This certainly isn't normal; I run it just fine on Windows 7 64-bit (aside from the game's inherent bugginess, which is no better on other versions of Windows).

The first thing I'd try would be uninstalling and reinstalling. Also make sure you let the verification process finish completely if you didn't do so the first time you installed it; if it says the file is corrupted the only way you can fix this is by downloading a new copy.
