Found this for a previous update: replace 7.0 by 11.0, might work.
-Close Premiere
-Move all folders from “C:/ProgramFiles/Adobe/Common/Plug-ins/7.0/MediaCore” to another location
-Start Premiere with “Shift” held down to clear out plugin cache/registry
-Put back one of the plugin folders and try to start Premiere again
-Repeat for each folder
