The user that is having the issue with not being able to see the EPM option when Right-Clicking in the report to Insert Member. I had that user try to do the Microsoft update fix. After going to the "How to Download and install the update" section and selecting the 'Download update KB2920754 for 32-bit version of Office 2013 he received the following message "No productions affected by this package installed on his machine." Then I had that same user log on to another users machine and he was able to see the EPM option when he Right-Clicked to insert member. It appears that the problem is designated to his machine only (possibly others but not majority of users).
If it is a Microsoft update issue, wouldn't running the steps in ticket 2107965 have come back with a resolution?
