"VM cannot be opened since it is already used in another Parallels Desktop window." This just started happening. I can open other VMs without issue. Can anyone offer a solution to this problem? Thanks! PD Beta 3036, OS X 10.4.8 - Macbook Pro
You have to delete the lock file. This issue has been discussed to death on this forum. Do a search on ".lock" for detailed directions.
Thanks joem! It would be nice if the error message actually mentioned the ".lock" file. How would I have even known to search for ".lock" in the forums?
