So basically I deleted GOG to fix a issue I had downloading a game because it kept saying Problem with connection while downloading, after I deleted the files and checked if there is any more gog files under the windows tab I tried to do a download with GOG.2 but it keeps saying that GOG is already installed and it will cancel the installation

What do I do

Note: I tried to restart my PC

I mean if all else fails... crying is always and option...

What you can do is try to find all files relating to Gog Galaxy and delete them, or download offline installers.

Yeah I tried deleting all the files but still pops up

Where can I find the offline Installer

1. Go to https://www.gog.com/account
2. Click on a game
3. Download the files underneath "Download Offline Backup Game Installers"
4. Run the .exe (should be in your browser's download folder)

Thank you it works now
