Question : Problem: VSTO Outlook add-in install on terminal server

We have created an Outlook 2003 add-in using VSTO along with all the security requirements using the instructions on this site: http://weblogs.asp.net/mnissen/articles/427504.aspx

We have tested the install on seperate XP Pro machines with no problems at all. We also tried a Windows 2003 server not running WTS. We are now trying to install it on a Windows 2003 terminal server and have had little success. Most of the registry entries are insterted along with the program and the pre-reqs (i.e. .NET 2.0, IAP, VSTO Runtime) . However the add-in does not get added to the list of COM-Addins and it is not in the disabled list under help and about. We have even set the project setup to install for all users.

Is there anything special about installation on a WTS environment (besides the change user /install or through add remove programs)
