Outlook Add-Id not starting

[Carlos Andres Guaneme Lugo]

Dear Colleagues:

We're facing a problem trying to run an outlook add-in for Outlook 2003. The
add-in installs and runs ok in the development environment (no surprises
here) but once in test environments with the proper prerequisites (VSTO RT,
..NET Framework) it fails to install. Additionallly, when we try to add it
manually, an error saying "XXXX is not a valid add-in" appears. Any ideas?


Thanks in advance.

It fails to install, or it fails to load?

Are you setting the security for the addin assemblies to full trust, as
indicated in the walkthrough for deploying VSTO addins?

If there's a load problem you probably will have to use Fusion logging to
see where the addin loading is failing. You can review the instructions for
that at
