Hi, I tried to install the latest release several times but it always comes up with an error while install script is running. The unfinished partial installation them pops up with: Parallels Desktop is unable to operate properly since it cannot communicate with one of its drivers. Try to restart the application to overcome this issue. If restart doesn't help, re-install Parallels Desktop. Note that Parallels drivers require a short time to be properly started and initialized. So you may need to wait a minute before trying to launch the application. Any ideas? Bye Ralf.
