I installed the game and added a patch and now the game wont work. I want to uninstall and reinstall but I cant find any option to do so. I tried deleting game manually and that got rid of some files but still cant see how to re-install from scratch?

1. it was a bad idea to just manually delete files

2. You didnt see uninstall under MORE > Manage Installation > Uninstall?

Uninstall is grayed out and not an option. I got rid of game and finally did reinstall it but now I have new insert disc error. Not sure why uninstall is grayed out.

what patch you want aply? Because GOG version contain unofficial patch. And one tip, if you apply some patch, don't rewrite deep6.exe and leave it that as it is, otherwise you get insert disk message.

?! you realize I made that post almost 2 years ago.

Well, this issue persists. Does anyone know the solution? I can't reinstall a game because of this dumb shit and no thread about it seems to answer how to fix it. How is this problem still a thing after 2 years?

I fear the only way to fix this trouble, if you deleted without using uninstall would to be purge the regsitry. not a fun thing to do
