I'm unable to download D1 currently and have had this problem on 2 PCs:

Through GOG Galaxy the download reached 90% and stops. Downloader continues to claim downloading is happening at ~ 2.0 MB/s. I've let this go for multiple hours without completion.

I'm unable to find the offline installer on the store page via the web any longer.

In GOG Galaxy the offline installer is listed under "extras" - clicking on the installer does nothing.

I'm unable to access my game.

This sucks man.

EDIT: I didn't notice that clicking the offline installer added it to my GoG Galaxy download qeue, so problem solved. Proper GoG Galaxy download integration should still be fixed, however.

I dont think that is a problem with Galaxy. I didnt try exactly Disciples 1, but I suppose problem with compatibility setup using Windows DISM command service. It require to star Galaxy exe as "admin". That Dism command prompt for compatibility used for some games - and Disciples one of them.
Also, real or virtual disk drive required for game configuration.


There is absolutely no problems with downloading offline installers - both from Galaxy or from web link:

Starting Galaxy as Admin does not solve the issue. The Download gets to 90%, then stops.

Got a reply from gog.com saying this is a general issue with Galaxy and certain games that they are working on.
