I installed the 64-bit Ultimate. My laptop: MSI GE70 Apache Pro, 16GB, Nvidia Gtx 860. When rendering various clips to the movie, the program crashed every time. At the settings of VideoStudio kanns not lie, all have been tested in mp4 on disk. 2 times the unit neubespielt. Fresh, So without further software I once can render a movie to the end 2. Once again the ordinary software was added, again only crashes. The support meant out because it worked on a fresh system, there is no bug. Should be noted that this is probably unrealistic, they wanted a large clip of me. Hab uploaded 1.6GB, present, 6 minute clip. Result: the clip was rendered in Corel in any format. Wow, an entire clip. I felt ripped off and have brought the expressed. In the next mail from the support, was, for the problem I needed a support ticket and it costs 19, 90 !!! My system is running bit with Win 8.1 64, my drivers are all up to date. Did then uninstalled the program and installed on my main computer, same system, also 16 GB, also i7 4.Gen., Asus board and again only crashes. I can only explain it to me as a 64-bit problem and unfortunately I had to remove the software. I tried the trial version of CyberLink Media Suite 12 and on the laptop already fully installed again I diced all possible clips that I had together and I have not had a crash. Maybe the problem has to do with Win 8. Anyway, who with VideoStudio has a problem, must pay and that is not okay!
