Why can't I use the program in my Windows 8?
The software doesn't work on Windows 8 because it lacks compatibility with this operating system. I have looked on their official website, but there is nowhere mentioned about the compatibility with the known operating systems, although from screenshots I have seen it can run on Windows, but not Windows 8.1.
Contact the developers of the application and they should provide additional info related to this request: http://www.vatechamerica.com/customer-support/technical-support/
