I am trying to upgrade nintex workflow 2013 to the latest patch. I started the exe and wizard opened up, but the wizard gets stuck at "Updating core solution components". In central admin under Manage farm solutions the -"nintexworkflows2013.wsp" is displayed as "Deploying" for hours. If I cancel the deployment the status comes as deployed. And the deployed details are such that it deploys to one Application and one web front end server (In actual there are 2 web front end servers).
Please help. Thanks in advance
