If you have 'Initial load behavior' set to 'load on demand' change it to
'StartUp'

In Excel, is the addin installed under Tools/Com Addins... as well as
Addins/Automation addins (if used for UDF's)

Hi all,
I'm trying to build an excel addin using c# and visual studio. In my
addin,
I'm generating a button which I want to be displayed as soon as I open my
excel. I did the COM registration also. The button is showing up but only
after I start writing a "formula" in an excel cell like (=sum, =count)
etc. I
shifted my create button code from Onstartup Complete and Onconnection of
Connect.cs but of no use.

thanks in advance
