I have a custom addin that works for outlook 2003 or above. I have installed it and working in several machines with outlook 2003 and 2007 (with xp and vista), but.. there is one pc with outlook 2007 sp2 /xp that doesn't display the tab "add-ins" in the ribbon (in the mail inspector), so , I can't access to the addin button.
I create from my addin a command in the command bar, so, it should display the addin in the "add-ins" tab in the ribbon.
I'm new with addins, so I don't know how to debug this issue...
I use in the addin redemption and .net 1.1.
I appreciate any help to solve this.
