Not one of my normal posts but I thought Id share this issue as if I knew the fix earlier it would of saved me about hour of my time. When installing SP3 the process was stuck at Languages for over an hour as per screen shot below.
After asking the question on twitter and googling. I could seem to find anyone else who has experienced this issue. It turns out that because System Centre 2012 Endpoint Protection was installed on the client machine, it was stopping the process from completing as it uses the “Same Engines” for Languages.
Because Endpoint Protection is forcefully installed by SCCM, I uninstalled Endpoint Protection and the Languages install then started to complete. The reason I uninstalled Endpoint was because it would be reinstalled by SCCM once it did its next walk.
Hopefully this post will help someone with the same issue I experienced or point them in the right direction
