    Greetings...  Recently I experienced a power failure at my office when I was running two different virtual machines.  Upon restarting, I am unable to connect to the machines as VMWare tells me "This virutal machine appears to be in use."  If I press the "Take Ownership" button, it immediantely returns with a dialog box indicating "Taking ownership of this virtual machine failed."  How do I unlock these machines?

    Strangely enough, even though it's 6 years later, with VMware Workstation 10, the answer is still the same. As community moderator wila states, delete any .lck or .lock files and/or folders you see, in the directory where the problematic VM resides.

    If you need further convincing the fix is that simple, see also my short video that demonstrates the fix. It'd seem that VMware would address this issue with a better recovery technique, given it's an error I've seen occasionally for many years myself. But hey, at least the fix is well documented!

    This issue already bit me once on Windows 10 and VMware Workstation 12, and the same fix worked just fine.
