I am trying to deploy an excel application addin developed in VS 2008/VSTO 3. We don't want to use ClickOnce as we deploy apps to our users via group policy and msi's are much easier in that regard.
I have followed a few walkthroughs for VS 2005 VSTO SE add-ins (http://msdn2.microsoft.com/en-us/library/aa537179(office.11).aspx
)... but they don't seem to work (I always get the 'This is not a valid office addin' error when I try and enable it in word. Do I have to do something different with VSTO 3 add-ins?
Has anyone got any step by step instructions on how to deploy vs 2008 office 2007 add-ins without using click-once?
