Microsoft Exchange Server 2013 upgrade to SP1 or RU5 or RU6 will fail with error message " The Windows component RSAT-Clustering-CmdInterface isn't installed on this computer and needs to be installed before Exchange Setup can begin."

Issue: While trying to upgrade Microsoft Exchange Server 2013 RTM or releases below SP1/RU5/RU6 that is installed on Windows 2012 Server to either SP1 or RU5 or RU6   error message "The Windows component RSAT-Clustering-CmdInterface isn't installed on this computer and needs to be installed before Exchange Setup can begin." may appear on the screen.

Following is the screenshot while performing silent upgrade


If you will check ExchangeSetup.log file located usually under C:\ExchangeSetupLogs\ folder you will find entries similar to the following:

[11/25/2014 05:04:26.0209] [1] Failed [Rule:RsatClusteringCmdInterfaceInstalled] [Message:The Windows component RSAT-Clustering-CmdInterface isn't installed on this computer and needs to be installed before Exchange Setup can begin.]

The link mentioned above as of today while I am writing this note is not working.

Following is the screenshot from the log file in question:




Solution: Install the required module using the following Windows PowerShell command whiand restart setup.exe program to upgrade.

Install-WindowsFeature RSAT-Clustering-CmdInterface

Following is the screenshot (ignore warning about automatic updates since I like to control updates on my servers)
