Thanks i'll have another go, im thinking my CD laser is knackered
I had a hell of a time installing on Vista. For some reason the copy protection on the disc really messes with it, sometimes setup would crash, or it would fail to copy files completely.
If you get the "could not load text/fonts" even when your fallout2.cfg has the correct paths in it, then your master.dat/critter.dat is screwed up. I suppose it's possible for other files to be mangled too, but those are the biggest. Problem is, Vista can't read those files off my CD to copy them manually or create an .iso image either.
Best bet is to install on a non-Vista machine and then copy it over, the game is self-contained in its own folder.
