Hi, I'm on Galaxy Client 2.0.17 and Windows 10 x64.
The game does not launch from the Galaxy Client, and when I went to the game's folder and double-clicked on RiMELauncher.exe, I got this window (attached).

There is no way to play the game but doubleclicking on the 'Launch RiME' shortcut in the main folder, or executing the main exe file at RiME\SirenGame\Binaries\Win64\.

Can the Galaxy launcher be fixed somehow, please? It would be nice to have my achievements unlocked...

There's a thread about this issue in the German forum and we found the solution:

1. Exit Galaxy. (Close it completely)
2. Move the file "goggame-1553712069.info" from the game's folder to your desktop.
3. Open the file with an editor and delete the line with the following entry:

"isHidden": true,

4. Save the file.
5. Now start Galaxy again and check that RiME is showing as "Not installed".
6. Move the file "goggame-1553712069.info" back to the game's folder.
7. Go to Settings \ Manage installation \ Import folder and select the game's folder. (Screenshot attached)
8. Now launch the game with Galaxy.

It totally works! Thank you for sharing it! :D
