You advertise these games as compatible with pretty much all versions of Windows, on the game's store page it even says it's compatible with Windows 8. I have spent weeks trying to get this game to work and still haven't found a fix. I have even asked around on this very forum and no one seems to be able to help. The game doesn't work on Windows 8.

I'm using Windows 8 64-bit and can confirm that Soul Reaver 2 works on that (even though it crashes occasionally).

Have you tried contacting GoG support team? They are usually very helpful with that kind of thing.

I have a physical copy of Soul Reaver 2 and it works on Windows 8.
