You can try my workaround I described here: https://forums.obsidian.net/topic/82949-203-the-game-refuses-to-start-runtime-error/?do=findComment&comment=1745528
First, sorry for duplicating the topic. It should be noted that the game works fine if you never install Galaxy client. There seems to be a bug in Galaxy's uninstaller that does not remove all of its libraries and as a result, the game tries to load them. This caused the crash as my libraries were rather old (July 2015).
The alternative solution (for those who do NOT have Galaxy installed) is to explicitly delete directory C:\ProgramData\GOG.com\Galaxy.
