I'm having some trouble in deploying the C# Automation addin on a user
machine.

To briefly tell you the situation, I had developed a C# Automation addin
using VS 2005 and it's working fine on my machine with Office 2003 . I wanted
to give this to another user for testing.So created an MSI with primary
output's Register property to "vsdrpCOMRelativePath".

Got it installed on the new machine ( with .net 2.0 framework and Office
2003).And started Excel and i can see the Addin in the List of addins (Tools
-- Addins), But when i try to enter the function in a cell it's not
recognised and on checking in the "Insert Function Dialog box" , my addin is
not appearing in the list.

I ran Regasm to ensure that the "Programmable" key is present for the dll.
And i can see that the dll is registered correctly

Secondly tried to GAC it. But without much luck... on googling a bit and
searching the msdn forums found an article
http://support.microsoft.com/default.aspx/kb/908002 .

I even tried the steps mentioned in this article. But still it's not working.

Any help to solve this issue is greatly appreciated. Please let me know if
you need any further info.

Thanks in advance for your help
