Windows apps won't run

I am running Desktop 4, build 3810, and Windows XP Pro with all the latest MS updates. I had a problem with my previous version of Parallels where something got corrupted in the virtual machine, or windows, or ???, and until I reinstalled Desktop 4, I was unable to get WinXP to run under Parallels. Not sure if this is related to the problem I describe below.
Anyway, now Desktop 4/WinXP Pro seem to be running ok. However, I can't get Windows Media Player to start. I click on the icon, get a short hour glass, and then nothing else happens. No app, no processes, nothing. Also, when trying to install a third party app (Charmed Quark Control software), I get a similar aborted startup.
Any suggestions?
How do I go about completely uninstalling Parallels, including the virtual machine stuff, and starting over?
Thanks

It looks that you need to perform Windows repair, just make sure you backup your VM before it

 

Thanks.
I pretty much got it sorted out without having to do a repair. One of the apps needed to have all it's folders sitting on the windows side of the file system, and wouldn't install otherwise. My other problem was with WMP and I just downloaded the most recent version and it installed and executed fine.
So, I am good for now.
