What I ended up doing was, I installed the game using the offline installer, then edited the desktop shortcut that was created during installation as follows:
Target:
"C:\Program Files (x86)\GOG Galaxy\GalaxyClient.exe" /command=runGame /gameId=1875167847 /path="D:\Games\GOG Games\Ghost of a Tale"
Start in:
"C:\Program Files (x86)\GOG Galaxy"
Also, this way the proper files for the uninstallation process are copied as expected. It's a workaround, I hope they fix this.
PS. Change the path to where you install your GOG games,mine is "D:\Games\GOG Games\"
