Matruchus: That is a very bad bug. Galaxy.dll has no place in the standalone galaxy independent gog installer.
Tarnicus: It's not just The Witcher 3. I downloaded Galaxy, installed Age of Wonders, removed Galaxy (as it is rubbish) and Galaxy.dll is still in my Age of Wonders folder. I would not have known to check if it was not for this thread. Am going to test out a standalone installer and see if it is there.
Edit: So I don't have Galaxy on my computer. I re-downloaded Age of Wonders and installed it, and lo and behold Galaxy.dll is in the folder. Date of file modified shows as 6/9/2010. I see GOG has invented time travel as well as installing a potential form of DRM on standalone installers. GG GOG :(
Edit 2: and after searching my registry after uninstalling Galaxy, "C:\Program Files (x86)\GalaxyClient\GalaxyClient.exe" still exists.
Edit 3: 63.8mb of files under ProgramData\GOG.com\Galaxy remained after uninstalling. The Galaxy.dll is hopefully confined to Age of Wonders. Strangely the Galaxy.dll is also on my Steam version of the game. Even more strangely is the Steam_api.dll file being on my GOG Aarklash installation, especially given I don't have the game on Steam.
This is for Crossplay nothing nefarious, use a dll watcher or program monitor there is zero outside connection.
Coelocanth: Well, I tried again, and I give up. Galaxy refuses to DL or install anything on any drive I designate. I've reinstalled, I've deleted the services GalaxyCommunication and GalaxyClientService every time. I've rebooted before and after uninstalling and reinstalling. I've grabbed the latest build of the client. I've tried installing the client on a different drive and having it DL and install games on that same drive. Nada. It tries to update as soon as it fires up and that fails. Every time (although why it would need to update when I have the latest build available from GOG's own site is beyond me). It will not DL anything to anywhere I designate (I don't have enough room on my C: drive, so it has to be on one of the other two, but it gives me an error and access violation every time).
So I'm done with Galaxy until it's out of beta (and I'm not even sure I'll try it then). Sorry GOG, but this is an epic fail in my eyes. Just keep links active for the old DLer and it's all good though.
i added a screenshot to show this works and there is a settingto modify install location for all games i have tested it with my NAS and can successfully install there if i like.
make sure to check that manual box
