I think the crack is only working with for example WinXP. His buisness PC is WinXP, his private PC is Win98... don't know!

Sorry I should have mentioned this, I guess I just took it for granted.
Both are Win XP machines and both are above the games minimum and recommended requirements. Both machines have windows completly up to date and nothing really seems different about them. Specs on the one that won't play it with crack are as follows;

Intel P4 mainboard
P4 2.6ghz CPU
512 mb ram (Dual Channel)
Geforce FX 5600 Video card
