Question : Outlook 2003 Add-In with VSTO: no permissions

i am using Visual Studio 2008 to deploy an Outlook 2003 Add-In to users in our SBS 2003 domain.
The assembly will not load, citing permissions (error pasted below).
I have tried signing the assembly with a strong name and a certificate, and even tried adjusting permissions with caspol.exe:

caspol -machine -addgroup 1. -url "C:\Program Files\Common Files\Microsoft Shared\VSTO\*" FullTrust

caspol -machine -addgroup 1. -zone MyComputer  FullTrust

Neither seems to get the assembly to load.
Any suggestions please?
Thanks


The customization does not have the required permissions to execute.

Answer : Outlook 2003 Add-In with VSTO: no permissions

Are you deploying ithe Add-in using a setup program?

If so, did you follow the steps shown in the link:
http://msdn.microsoft.com/en-us/library/aa537179(office.11).aspx
(the section "Walkthrough: Enhancing the Outlook Add-in Setup Project")
The project SetSecurity contains the custom actions that do all the security settings for you. I used for an Excel Add-in and it works OK.
