Yes that function isn't supported on XP, although they could (probably) just as well have used a similar function that does work on xp (e.g. GetModuleFilename).

Hi... Thx for the hint... Unfortunately it tells me that it can't open the Doom3BFG.exe...

I found the original XP version on steam .. I have no experiences with steam... Can I download a setup put it on a USB drive and install it on my XP machine? I found a way via the 1.3 patch to make it playable without the client... But there is no detailed explanation about game installation.

Alright folks... I got the steam version working with the patch... But had also to install the enhanced version to get graphical enhancements working. But now it runs

According to my notes the Doom 3 BFG version from Steam works fine on XP 32bit. You can use steamless to remove the steam requirement.
You can also use rbdoom 1.1.0 preview3 (You might need to change major and minor subsystem in the game executable)

The retail Doom 3 works fine on XP
You can also use dhewm3_1.5.1pre1_win32 (You might need to change major and minor subsystem in the game executable)
and also fhdoom

Doom 3 is pretty simple, if you are referring to the Steam version as long as the Steam requirement is removed just copy the files over.

Thx... Looks like few possibilities to try out in the future... For doin this the first time with a steam game I am really happy for now... Didn't think it would be that easy...

The gog bfg version will not be playable anyway on XP... right?

I don't have the GOG version but I'm guessing it's the galaxy dll that added that dependency.
Likely not worth hexediting and wrapping since it's easy to replace the game executable with an non-infected version or just use a port.
