FYI Update Rollup 3 for Microsoft System Center 2012 R2 - Virtual Machine Manager (KB2965413) Stops SCVMM service starting

Question

I just applied update:
Update Rollup 3 for Microsoft System Center 2012 R2 - Virtual Machine Manager (KB2965413)
and (KB2965414) but it failed to install.
After a reboot I could not login to the VMM and the service would not start
An event id 0 was reported with:
Service cannot be started. System.Reflection.ReflectionTypeLoadException: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.

After I removed the update the VMM was able to start, no reboot required.
When I have time I will try to apply both updates again successfully and see if the issue still occurs.

FYI.  I've had the same issue after I installed Update Rollup 3 (KB2965413), seeing the exact same error on event log.  Tried to start the service manually, getting service unable to start error.  This is a machine running
with Windows Server 2012 Standard.  Solution for me is simple. I just install
KB2965414 (Update Rollup 3 for SCVMM 2012 R2), reboot the server, and the SCVMM service auto start up by itself.
