Tried an individual game install and tried installing Galaxy 2 off the install page. Both downloaded files run but fail at the end with message: "Failed to download necessary files..."

The link provided in the error message is broken.

New Win 11 pc. No virus protection other than default Windows.

Thoughts on alternative download or fixing this one?

Solved for me. Not allowed to post links currently, so...

Search for "gog_galaxy_20_web_installer_fails" in the forurms, posted by BDaddy1969 on April 27, 2023.

The solution in the second post posted by Ice_Mage points to an HTML snippet. The link you're looking for is the downloadlink at the bottom that starts with HTTPS and ends in .exe.

This JSON file should point to the latest versions of GOG Galaxy for the foreseeable future. The first link that ends in .pkg is for Mac and the second that ends in .exe is for Windows.
