When I try to start Ufo enemy unknown from windows xp the graphic error occurs and I see the game twice on my screen. It works under win 2000 but not with my win xp.
Does anyone have a hint to fix it?

Not speaking your language, here it is.
Do you have the gold windows version of the game or the regular dos one? If you try DOSBox you should be able to run the pure basic DOS version of the game, just increase the cycles (if you have a fast enough PC). If you have the gold version then there should be one or two ufo executables there. If you have an Nvidia card, they have a problem with that version and you need to use one special patch that exists for that reason, first.
Am I close enough?

Please post in english or I'll have to lock this thread up.

If I ufo enemy unknown of Windows Xp start see wants I the picture 2x above one another. Under windows 2000, it does not function however just in xp. Does someone have an idea?
that is offcourse to say:
when I run X-Com1 in windows XP, the picture splits in two, one on top of another, and in win2000 it won't run at all :cry: , please :help:

now was that so hard to do samdelin? (at leat the top part)
War das ja so hart zu machen, samdelin? (An leat der oberste Teil)

where do i find this "Nvidia patch" ?

That would be very helpful?! :blink:

I don't see why there might be a problem if someone post in their native language? This should be helpful forum, and not all of those who need help speak English.

As for the question, use DOS version with latest DOSBox.

Closed, rule #3

As for the language problem, this board is english and this is not a matter open to discussion. The only reason why this board is english is because it is the current world language.
