GOG games that I have installed are not showing up as being installed. The install button is lit. EDIT: solved

The correct drives are showing and the files are there. They will launch with shortcut. I was really trying to update Tomb Raider Remastered 1-3. They dont show up as being installed on website either.

Edit: never mind. i forgot I had migrated my installs to my brand new computer that died after two days last week. I'm currently awaiting the arrival of a replacement that hopefully lasts much longer.
