Live2D 5.0 alpha won't open
I've double clicked on the application twice and it would not run. I've reset my pc, deleted the temp files, made it the only live2d application installed on my computer and reinstalled it on a different drive. Did all that and it's still not working. However if I ran the 4.2 version it works but I use 5.0 for the ease on my eyes for the dark background setting.
