Error:
Exchange 2010 SP3 installation hangs on languages installation.
Solution:
Upgrading to Exchange 2010 SP3 starts out fine. Later on during the installation when the task to install language just hangs and the progress bar doesn’t move at all.
As this server was running System Centre 2012 Endpoint Protection, i uninstalled it at this point and within 2 min the Exchange 2010 SP3 Setup continued and finished.
After the installation System Centre 2012 Endpoint Protection was reinstalled again.
Hope it helps.
