Outlook plugin only usable as admin user?

Outlook plugin only usable as admin user?

Hello,
I installed the outlook plugin. I needed to do that as adminstrator on my system (Win2000).
When I am looged in as administrator and start outlook 2002, than the zoho plugin shows up.
However, when I log in a "normal" user, than the zoho plugin is not available in outlook. It is like if it is not installed.

Any idea how I can use the zoho plugin as standard user?

Greetings,
Frank
