The Virtual Hard Disk 0 has wrong access permissions or is used with another virtual machine

I had this problem this morning with a windows 10 virtual machine.
After trying various solutions from the forums I ended up with this process which eventually fixed the problem..

1: Resumed the virtual machine in Parallels desktop and waited for the error message
2: Stopped the windows vm process with mac Activity monitor (Parallels couldn't stop it)
3: In the Parallels vm configuration, hardware tab, disk page, changed the source to disconnected
4: Restored the windows vm image from time capsule backup last night
5: Exited Parallels desktop
6: Restarted Parallels desktop
7: In the vm configuration, hardware, disk page, changed the source to the restored windows vm image
8: Closed the configuration page
9: Restarted the windows vm

Everything then ok
 
So restoring a Time Machine backup of the virtual machine did the trick. We're glad to know that it worked for you. And thank you for sharing the steps in detail.
