I am attempting to upgrade from 5540 to 5570. The installer is at the Install Parallels Desktop window with the subheading of Installing Parallels Desktop. The information in the window is Preparing Parallels Desktop with a progress bar that shows only a very tiny amount of gray (progress) with the text below the bar Running Parallels Installer script. The problem is it has been at this state for over 60 minutes with no progress shown. Is there further information you would like me to gather to assist in troubleshooting the issue?
