Problem Installing CU7

Hi,

I have the client tools (CU6) installed on one of my servers. I am trying to run the CU7 installation in order to update the server. As soon as setup finishes the Copying Files step I receive the following error message:

The Type Initializer for Microsoft.Exchange.Management.Powershell.CmdletConfigurationEntr (line is cut off)

threw an exception. Could not load file or assembly 'Microsoft.Exchange.MailboxLoadBalanceClient Version=15.0.0.0 (message is cut off).

Any ideas how to troubleshoot this?

Thanks,

I. Kinal
