I'm getting the same issue. The program is loading up but once it tries to bring up the screen (Which I can see the logos and everything before it goes white) it goes white. Like the software is trying to start up but then keeps going in and out. Flickering.

Hmmm, I'm on it right now. No issues currently.

Are you kidding me fuckign GOG? Whyt you DIDN'T answer for thsi CRITITCAL error?
Custoemrs cant acces their games but you have this in your ass!!! Fucking ereror makers!!!

I can't understand what you're talking about, GOG Galaxy is not necessary to run or download your GOG games.

I'm using Windows 7 and I have the same blank/white window with the latest Gog Galaxy version. No solution found to solve that problem.

I happily play my games without Galaxy and it works.

Problems with Galaxy you should either take up in the Galaxy sticky thread or contact customer support directly.

If you want a working client you need to go to Steam.

Today, I tried again to install GoG Galaxy, and this time there was no problem of "blank window" as before. The difference? This time I did the installation without customizing the installation folder! The first time I stupidly thought that, in 2019, it could be changed without problem: false! I have done other installation tests, and for me, it works fine only if I install GoG Galaxy in the default installation folder (C:\Program Files\Gog Galaxy\).

It annoys me a little because I would prefer to put this kind of software elsewhere, but at least it's working now.

I had the same problem. I tried running GoG Galaxy in Windows XP compatibility mode and it started working.
I hope it'll work for others having this issue.

I've never had an issue with Galaxy but I also have Windows 10. What OS do you use?

Just managed to repair the issue.
1. uninstall gog galaxy
2. download a game you want to install
3. the installer will install the gog galaxy, but it will work this time.
