RC2 activation locked...need help getting file

I just purchased a Vista Home Premium to replace the RC2 I've been running periodically. I received a message that I had one day to activate or be locked out which occured. I've purchased a retail version and plan to do a clean install however, one file was left over in the RC2 install. Its on the desktop and I can not access it. What options do I have? Is there a backdoor way through the Parallels folder in OSX to copy this file over?

EDIT: I'm using build 3214

 

Hello,

It is possible to extract the required file by means of Parallels Explorer. The other way is to create a new VM, install Windows and connect the required .hdd file as a second drive,

Best regards,
John
