crisby_pancakes: Same issue, downloaded to 100 percent then got an error/failed to install and now greyed out and unable to install.
If you got 100 percent and got the install notification error check the install folder. I had the same issue with the install option being greyed out. However, all the game files were there and I was able to play the game. It was just not recognized by Galaxy.
I sent a help ticket to GOG. I dont know if they fixed it but a few hours later when I ran Galaxy it automatically recognized the game as installed and I was able to install the armor DLC via Galaxy.
Zenoxi: Install button works now!
I've seen similar problems on Steam so I'm not to mad. It happens so I'm going to give GOG a pass. Great company, and hopefully their releases go smoother for people in the future.
I have seen this happen at Steam a few times as well and Galaxy being beta I can give it a pass as well.
I was still able to play the game and while Galaxy was running my GOG name was displayed even if Galaxy did not recognize WL 3 as installed.
