I transferred my games to a new hard drive and had Galaxy Scan Folders for GOG Games by pointing it to the new drive. It worked for most games but there are a few dozen which don't show up as Installed. The problem is that I can't seem to get Galaxy to install them. If I go to Owned Games, select one of the games and go to Manage Installation there is no option to Import Folder. I don't mean that Import Folder is greyed out, the option simply isn't there. If I try to install the game through Galaxy the pop up appears to ask where to install but after that nothing happens. I tried reinstalling a game using the offline installer but that still doesn't let Galaxy recognize it. Has anyone run into this before?

I have the exact same problem.

All the best

After some back and forth with GOG Support I got it fixed after following these instructions:


Hello,

Please try making a clean install of GOG GALAXY.

First uninstall GOG GALAXY by running the unins000.exe file located in the GOG GALAXY installation folder (by default C:\Program Files (x86)\GOG GALAXY).

Then make sure that following folders are also removed:
C:\ProgramData\GOG.com
C:\Users\All Users\GOG.com
C:\Users\*username*\AppData\Local\GOG.com\Galaxy\Configuration
where *username* should be your Windows Account Username.
You made need to show hidden files and folders in the "Folder and search options", if you haven't done so already.

Restart your computer. Then download the latest version of GOG GALAXY from our website:
http://www.gog.com/galaxy
and run the installation as administrator.

After that please try to re-import your games.
