Sure! First, navigate to where the launcher is. Then, right click it and go to Properties. In Properties, select the Compatibility tab. Enable Compatibility mode, and select 'Windows XP (Service Pack 2)' from the dropdown list. It worked for me, so it's bound to work for at least some other people. No, it's not just older…
I launched the launcher in XP Compatability Mode SP2, and it appears to be working! The game is patching! If I can get in game, I'll let you guys know.
