I have 2 problems with powerpoint 2016 that are probably linked, the first one is that i have a pptm file from PP 2013 which when i try to open it with 2016 it always crashes (i think it's because it has some macros in it) and the other problem is that on Developer tab the buttons for Visual basic and Macros are gray thus i can't use macros at all, I have already set macros security to minimum in options it didn't help
