I had some issues with r2 not even opening on Windows 8.1. The window would open, spin its wheels for a couple of seconds, then crash with a "Spriter.exe has stopped working" message. I thought it was something to do with a recent monitor upgrade (higher resolution), so I tried quickly dragging the window to my second, older monitor and it opened... once. It likely had nothing to do with dragging the window because that trick just never worked again, after dozens of attempts.
I uninstalled r2, reinstalled r1, and it opened just fine. R1 pointed me at the beta instead of stable release, but I tried it anyway. Lo and behold, it worked, but I got a sneaking suspicion when the window flashed briefly and loaded the video help popup. I noticed that the video help window opened at about the same interval as my previous crashes, so I unchecked the "Show this at startup" box and closed Spriter out.
It opens just fine now. I've opened and closed Spriter about 10 times with no issues, save one. If I go to Help -> Video Help, Spriter immediately crashes with the same "Spriter.exe has stopped working" message as before.
