Not enough information to go on.

What version of Outlook, what version of Windows?

Outlook 2007 , Windows XP on development pc.
Outlook 2003 , Windows XP on production pc.

Add-in is version 2003

Are you installing for "all users" or for "current user"? Are you
installing the same way with both methods?

Installing for all users and I have set it to default in setup.

Are you running setup.exe or the msi? Does this happen on the development
machine or other machines?

Happens on development. Running setup on production pc also does not work.

Does the addin show up in the COM Add-Ins dialog? Is it checked? Does it
show some sort of load error?

No to all.

Of course on development if I install from within vs 2008 IDE it works.

Are there any entries in any of the event logs related to this?

Not that I can see.

Are you running as admin or as a user?

As Admin.
