Installation via Galaxy fails constantly.

Installation via Installer works fine, but after importing the folder Galaxy starts an update, which leads to "broken installation" message.

Same here.

Same problem here. The game does seem to work though, so far it starts without problems when directly using the .exe file in the installation folder. Only Galaxy shows the installation as broken. Weird!

I also am unable to download through Galaxy because of "Installation Broken"

It would appear that installing the game via gog.com (not the GoG Galaxy program) and running the game via the .exe or shortcut seems to alleviate this problem.

As it stands (6/10/2016), the GoG Galaxy application reads the installation from either source as 'broken' and thus will not launch the game.

Same problem here :(

Same problem as well.

This has been reported to GOG's Support team, right?

I only ask because there are a lot of "me too" replies to this thread, and not a single mention of a support request.

Yup. It's fixed now :)
