tjplump: when i try to install the software it gets past the installation phase then just says that there is already an instance of GOG 2 running on my PC and i have never downloaded it before. has anyone else got this problem or found a fix?
It complained that I already had GoG Galaxy running, but it was because I head GoG Galaxy 1 running. However, it wouldn't stop complaining even after I shutdown Galaxy 1. I had to actually exit the installer and try again for it to work, which does imply that there are issues with how it detects that GoG Galaxy is running (like maybe it doesn't actually redo the check like it's supposed to when you hit OK), but I wouldn't have expected it to complain if you'd never installed any version of GoG Galaxy before. Are you sure that the problem isn't that you have GoG Galaxy 1 running in the background? If you definitely don't have any version of GoG Galaxy running in the background, then the installer has a bug.
