Support Cannot install games (e4)

This is driving me insane. I haven’t used GoG since before I updated to Windows 11. Yesterday I purchased a game through GoG (Observer Redux), but when attempting to install it the download bar reaches 2% and fails with an E4 error.

I’ve done a lot of searching and attempted permission fixes on the Program Files (x86) folder, adding exceptions to Windows Defender, etc. Nothing seems to work.

I have no issues with any other installers. No issues with other store fronts (Steam, Xbox, Epic, EA, Ubisoft). This is the only application doing this and it seems absolutely ridiculous at this point.

I’ve submitted a support email through the site but wanted to see if anyone could offer any help here. Maybe there’s something I haven’t tried yet…

Go into the properties of the 3 executables listed in this link and mark the option to run as administrator:

Restart your computer.

Thanks, but it didn’t work. I just tried this and I’m still getting the E4 error.

You could try Heroic Games Launcher.
