"You don't have enough rights to use this virtual machine"

I get this message when I try to start Windows 7 in Parallels. It was working fine, now I get this message every time.

I have repaired permissions. I opened the .pvm file in "Get Info" and made sure that everyone had read/write privileges. I also added myself as a read/write user even though I am the administrator.

What else can I try? I don't want to lose the files that are on the virtual machine and I certainly don't want to go through re-installing Windows and the applications.

Any ideas?

 

I had this problem too, today, after moving a VM from one user account to another, even after running

Code:

 
cd Documents/Parallels
sudo chown -R username "Windows 7.pvm"

(where "username" is the Mac username who should own this). The trick, I eventually discovered, was to explicitly grant yourself user-level rights. Once I ran:

Code:

 sudo chmod -R u+rwx "Windows 7.pvm"

then I was back in business.
