Arrgh COM+ dll registration Hell

I have made a dll with the following references:

3 VB application, procedures references (must be there i guess)
OLE Automation
EXOLEDB Typelibrary
Active X Data objects 2.5
CDO for Exchange Library

The dll will run on an W2K+Exchange server. I can register it and create the COM application on my server, then i send the dll to another organisation and then
When they create a Com+ Application and tries to create the Component in this application, it comes back with an error (see attched picture). I have searched MSDN and newsgroups, but cant find the answer to this. I have used a lot of time trying to figure out the Error.....any suggestions would be appriciated.
