Running a Windows 10 machine and when the download completes it starts configuring then immediatly reboots. Once the machine comes back up it starts to download all over again. Help?

I guess you're using the Galaxy client for downloading and installation. If so, download the game manually from your library on GOG.com and the install it. Galaxy is still beta and might be the cause for the reboots.

Yeah, I figured out what caused it about two miniutes after I posted this. One of the prerequiites requires a reboot but it couldn't tell if it was completed so it is an endless loop. I am using the client so I may put it in as an issue for that so it can be fixed in future versions.
