Can't have two VM's running at once

Hi there, I am having issues running two VM's at once. I am using VM Workstation Pro 16 (16.2.2). I have checked my log files and it appears that when trying to launch another system while one is already running, the system tries to use "vm-4.scoreboard" but fails, as I presume it is being used by the system that is already powered on.

Anyone know how to fix this issue? Attached is my log file.

Thread reported so moderators know it should be moved to the area for Workstation Pro, since this has nothing to do with a vSphere security advisory.

This typically happens when you have two virtual machines both living in the same folder.

The solution is to untangle those two virtual machines and move each to their own folder.
I strongly recommend to make a backup before you do that.

This sounds as if you had a part of the vmdk opened by another VM - of course that would prevent to start the VM.


Do you need support with a VMFS recovery problem ? - send a message via skype "sanbarrow"
I do not support Workstation 16 at this time ...
