I have a Windows 2008 Server and I attempted to install SP2. There was a
power outage in the middle of the install and I think it corrupted a bunch of
stuff.
When I go to Server Manager, no matter what I click on (Roles or Features),
I get:
"Unexpected error refreshing Server manager: no signature was present in the
subject. (exception from HRESULT: 0x800B0100)
In the Event viewer, I get:
Installation Failure: Windows failed to install the following update with
error 0x80070643: Windows Server 2008 Service Pack 2 for x64-based Systems
(KB948465).

Windows Servicing failed to complete the process of setting package KB961260
(Security Update) into Resolved(Resolved) state

-----------------------------------------
When I tried to install SP2, here's what I get:
A system error prevented the service pack from installing. Please download
and run the "check for system update readiness tool.
I installed that tool but I don't know where to go from here.
