Corel's final answer to me was upgrade to Windows 10 and buy VideoStudio X9. They said Microsoft had released a batch of security patches that made VideoStudio X7 and below no longer compatible with windows OS7. Sounds like a lame excuse since I have other video editing programs that still work great with these so call security patches. Corel has close out my complaint with them with no solution to make VideoStudio X6 work.
For me it's so long Corel, there are other program that are just as good as your and they work.
