I'm trying to add custom icons I created in Photoshop to show up in my Word 2016 docm file.

I've read and tried to use Greg Maxey's posts but they don't work in Word 2016.
For example, after I *finally* found the 'Custom UI Editor' I tried loading the .docm file.

I already have macros set up in the .docm and the QAT in the docm successfully runs the macros.
The only problem is, they all use the same 'built in' icon.



So, Greg says I was supposed to see a CustomUI.xml file and I could just click 'insert icons', then load the icons into the docm.
NOT SO. There is no CustomUI.xml file shown and the 'insert icon' button & menu item don't work.

I did successfully create a .zip file of the docm and in the zip, inside the 'userCustomization' folder, the CustomUI.xml file actually does exist.
I tried editing that but Word ignored my image="icoRF" attribute and replaced it with the dreaded green circle.

So, how do I *really* get custom icons onto the QAT in Word 2016??
