I originally had JDK installed and had the same results, then I installed JRE when I went around uninstalling and reinstalling everything and had the same results. The issue does persist after logging in, And then I can't actually tab through to launch after logging in because the cursor kind of gets stuck in the change log, can't tab past it so I've not been able to use the launcher for anything since downloading.
Edit: I'll be damned, disabling my antivirus seemed to do the trick. What the hell Nod32, y u do this?
If anyone else experiences this issue, from what I can tell you only need to disable the Antivirus before launching, once the launcher is up and running you can reenable your antivirus without your shit moving around everywhere
Thanks for the help, Chefsbrian!
