Excel Add-In: why I have to add COM in every time in Excel

Hi Everyone,


Anyone knows why each time when I open the Excel, my Anaplan Excel Add-in check box is lost?

I have to manually add it back in, by clicking the below check box "Anaplan Excel Add-in"?


How can I make it there always available by default?


It worked for me in the past, but did not work now since I upgrade to Windows 10.


Thank you,
