I am trying to enable the VMware Update Manager Client 1.0u2 1.0.0.63972

When I click on the Enabled checkbox I get an error message

"The VMware Update Manager cannot accept requests now because VirtualCenter server cannot be reached, or the database cannot be reached, or it is in the process of stopping.

I am running VMware Infrastructure Client Version 2.5.0 Build 104215 with VirtualCenter Version 2.5.0 Build 104215
