When I tried to power on the Virtual Machine (VM) this morning I was not able to power up the VM and there is an error message:

This virtual machine appears to be in use. If this virtual machine is already in use, press the "Cancel" button to avoid damaging it. If this virtual machine is not in use, press the "Take Ownership" button to obtain ownership of it.

Configuration file: C:\Users\<UserName>\VirtualMachines\<VMName>\<VMName.vmx>

So when I try to clicked the "Take Ownership" of this VM client and failed.  It keep on saying The virtual machine is in use by an application on your host computer but i just powered up my PC so it shouldn't be in use by anyone else.

Taking ownership of this virtual machine failed.
The virtual machine is in use by an application on your host computer.
Configuration file: C:\Users\<UserName>\VirtualMachines\<VMName>\<VMName.vmx>.

Below are the steps to resolve this issue and it is quite straight forward:
I recommend taking a backup before deleting any VM files, In case of any unforeseen or unprecedented occurrence.

In Windows Explorer, navigate to the folder which houses your VM files and Delete or Rename the sub-folder named "VMNAME.vmx.lck"

For example, if my VM was named as SANDUEL the folder to rename would be SANDUEL.vmx.lck. In this case, I rename the file name from SANDUEL.vmx.lck to SANDUEL.vmx.lck_old. This action is to allow when the VM power up, it will automatically create a new file.

Then now try to open up the VMWare Workstation and power on the Virtual Machine Client.

Now, the VM client should start up successfully.
Try that and tell me if this is working for you.
