It does not work, it has crashed 8 times. I've reinstalled it twice and the problem is during installation of the Parallels Tools. I've jumped back to 5 until they come up with a fix.
I received a reply from Tech Support. Having Application Enhancer on my computer was causing the problem. By adding DiskWarrior to the Master Exclusion list resolved the problem and it now works great.
