If there's a European version that's different from the US version, it may already be patched. The only patches I can find are for the US version.
***Mobygames*** lists European releases seven months later than the North American release.
Don't use autorun to install it. Be sure to right-click the Setup file and choose to "Run As Administrator" even if you're logged into an account with Administrative privileges. Also make sure it does NOT install into C:\Program Files. The game is so poorly made that it wouldn't surprise me if it didn't install properly on many computers.
