Microsoft: Setup Wizard for Exchange Update Rollup Ended Prematurely

The installer fails with the following error messages:
"Setup Wizard for Update Rollup 5 for Exchange Server 2010 Service Pack 3 (KB3184728) ended prematurely because of an error. Your system has not been modified. To install this program at a later time, please run the installation again."

<< Cause >>
The reason for the error and why the Update Rollup installer is “ended prematurely” is because the server has User Access Control (UAC) activated on the server. For good reason, it is not recommended to disable the UAC.

<< Solution >>
The recommended process for installing Update Rollups on the server, is using an elevated command prompt (Open a CMD with Run As Administrator) and make sure the Update Rollup is located on a local drive of the server and start the installer using:
SYNTAX example: msiexec /update <UPDATE .MSP FILE>

How to Start Setup Wizard:
msiexec /update Exchange2010-KB2917508-x64-en.msp

How to install the Update Rollup unattended (silent) add the following parameter (/quiet):
msiexec /update Exchange2010-KB2917508-x64-en.msp /quiet
