So i just bought the game on GOG and started to download it. When it was done it said "intstallation failed". Then i tried to repair the game, it also just said "installation failed".
right under the installation failed text it says "1.31 (A). When i click there a window pops up where it says:

Update 1.31(A) (22 March 2017)
Added support for Cloud Saves in GOG Galaxy 1.2 and newer


help what do i do?
