Exchange 2010/2013 CU stuck at Languages install

This simple solution can save you a lot of time.

This issue can happen on the upgrade of Microsoft Exchange 2010 and  2013 when you apply a CU. The upgrade gets stuck at Languages, step 9, forever.

It turns out that the solution is very simple, this happens because System Center 2012 Endpoint Protection was installed on the server automatically by the SCCM, and this software uses the “Same Engines” for Languages.


  1. Uninstall the Endpoint Protection on the server.

After uninstalling the Endpoint Protection, the Exchange update will continue.

When you do the upgrade of the Exchange CU finish, you can restart the server and install again the Endpoint Protection.

Hope this saves you some time!
