Installing Entity Unlocker


We are using Performance Center 12.63. When users try to edit a test they get the message.

"The test is locked for editing. It is being edited in a different session. To unlock entities are are locked by you, use the Entity Unlocker Utility"


Can you tell me how to access this Unlocker?  The download button is grayed out and it needs to be enabled by admin but I'm not sure how to enable it.
