Did follow your directives exactly. Next time I doubleclick .bim file it opens correctly. I build and deploy, but now I cannot use the analyze in excel function, it says some security issue has occurred and the data connection is disabled. If I create a new excel sheet, data connection, AS Server, I now have my self-created meaures listed, but still also has the ___Count of Models.

I close the solution edit the .bim file back as it were, save, open in ssdt, build, deploy, and it has reverted to same old - same old, ie analyze-in-excel is working again, still showing ___Count of Models.
