When I click on Parallels Desktop, it acts like it's not installed. I get the OS Installation Assistant asking me what I want to install. I have been running Parallels with no major issues for a couple of months. Mac OS 10.4.11 and Windows XP. Any ideas?
do you have an .hdd file?
If so please try in 'Select Operating System installation mode' choose 'Custom'. At a certain point choose 'Use an existing hard disk image' and then choose a path to your existing .hdd file.
