When I activate MS Office Excel 2016, my self-made macro for customized ribbon and Add-in files are loaded, but addins cannot be activated.
Although the Personal.xlsb is in the suggested location, C:\Users\myusername\AppData\Roaming\Microsoft\Exce l\XLSTART, it's not loaded.
When add-in button is selected, error 9 shows up.

However, when directly ovened Excel through the Personal workbook double click, everything's working fine.
What's wrong?
