Installed with success Parallels Desktop 7 with Windows 7 Home & Premium edition.
I did not have to register with Microsoft nor give my name, just put in the registration key. It seems that I am classified as an administrator only. Do I have to do something about that?
Many folders in Windows are just locked and there is no way I can modify the access rights of those folders.
As an administrator you can grant yourself access to all files.
from the main menu select Computer:
then right click Local Disk C drive
select Properties
a Local Disc(c:) Properties window will pop-up
select Security-
under Group or user names: select Administrator
make sure that in the area below Group or user name
Allow is checked, this should grand you access to all files on the computer.
