I'm trying to get Movie Star 5, running for video editing. I was able to install it for them without any problems an can launch it mostly, when it tries to load Font: Lao UI it halts an just stays there with the splash screen an the Unit has to be restarted since, it can't be ended in task manager. Have Windows 8.1 Professional, an I think a lot of the updates that are required an released by Dazzle. I also, had to set it to compatibility an run it in Windows XP SP 2
