How to fix the "Could not open virtual machine" vmware error.

Hello,

Today I got the following error when tried to open a vmware virtual machine:

Could not open virtual machine: C:\vm\cent4\Red Hat Enterprise Linux 4.vmx.
This virtual machine appears to be in use.

To fix this error I have found that it is enough to delete a lck file
from the "C:\vm\cent4\Red Hat Enterprise Linux 4.vmx.lck\" directory.


Thanks,
Sergey.
