I have encountered this issue several times over the years. Sometimes, it can be fixed by right-clicking on the PVM file and selecting “Show Package Contents,” then right-clicking the .hdd file and selecting “Get Info.” Scroll down to”Sharing & Permissions.”

If the staff permission is No Access, change it to Read & Write. All users who should have access to the Windows file should be Read & Write.

You may need to enter an Admin password to authenticate. (Parallels should of course not be running when you do this, and you should reboot afterwards, just because...)

This doesn’t always work for me, but it has helped enough to be a good tip.
