CharlesGrey: You should contact GOG to see if they can make up for it with some store credit at least. And to make sure they fix these issues, of course. They're not going to "dethrone" Steam with a games client that randomly wipes HDDs. :/
Thanks for the advice, but I'm not so sure about that. After all, it was a beta client, and I think you have to live with the risks involved in participating in the beta. At least I've reported it through the bug report platform.
Maybe this is actually a feature: Galaxy recognized Steam installations on OPs HDD, and decided to perform some kind of DRM exorcism. Working as intended. :P
I was able to LOL hard at this. :D But then you'd have to say the exorcism happens in an uncompromising way, without any fear of collateral damages. xd
Foxhack: I'm sorry for your loss.
I'm even sorrier GOG threw all their support at this poor excuse for a client.
Thank you!
cogadh: Doesn't Galaxy specifically tell you not to install it in the same directory as your games? I seem to remember that from either a warning in the installer itself or maybe from the FAQ.
I can't remember seeing an explicit warning. Generally, I think now it's a good idea to include a warning explicit enough in bold letters and with an exclamation mark.
BKGaming: I know some people won't like this... but right now, Galaxy works pretty well as long as you leave stuff to there default settings. I've never had a major bug yet by keeping everything as default (as far as the folder are concerned).
I'd expected Galaxy, even in beta, to let you set your own installation directory without anything as severe as what I experienced yesterday happening. Obviously, it was a wrong assumption.
skeletonbow: Oh, quick tip: Do *NOT* install your games under the folder where GalaxyClient is installed. That would be bad. Like, really unpleasant bad.
But if I'd installed GalaxyClient under a different folder, say \programs\, then it might have erased all my non-games programs instead. It was just a logical decision to place Galaxy in \games\ since it was gaming-related, so initially I had \games\Galaxy and \games\steam.
The best thing to do apparently is to install Galaxy in a separate Galaxy folder. I know now. :/
