Deploying vb.net english query application

Hi,

I'm attempting to distribute a vb.net english query application to a client, however, when the client runs the application, it crahses when it tries to create an instance of the "Mseq.Session" object.

As far as I can tell, the interop and the original dll are being included in the setup correctly - are there any special settings (such as com registration, system etc), or other files that I should be including? Or are there any other prerequisits for the client's pc before I can expect the software to run?

Cheers,
Tinium.
