FloKaj: I think the 1.04 "patch" was only some kind of "fix" to make the game work on Windows Vista and 7, nothing else.
yeahm that was the one you had to pay for. it was not really a vista/7 fix but a fix for issues the gamw had with modern video cards, although they labelled it a Vistat patch.
I wondier if the guy saying the game was not pathced to 1.04 has tried he GOG version. I needed the 1.04 patch to run the game on my current computer before I bought the GOG edition, but the gog edition runs fine on my computer with a modern video card (GTX 670)..
I suspect GOG put it own version of the video card fixes in it's version. (Fixing older games problems with modern vidoe cards is SOP for GOG. issueAnyway, if it was not working on modern video cards, this forum would have been flooded with complaints.
