I use Paralells many years, and I was satisfield. I use OSX 10.11.6 and Windows 10. Now I bought PD13, installation was OK, but P Toolbox does not work. Ifoud the file in the application, and I could start it, bot in the same time I have a message about the failed installation. When I start the intallation again it finish at 51%. How I can go back the previous version or repair it?

And a lot of thing doesnot work in the Windows!
