System.IO.FileNotFoundException: The specified module could not be found.

Hi

I am using static binding i.e the use of dll of MS OUTLOOK 2003 in my Windows application to extract FROM,TO,CC,BCC,MESSAGE email addresses and their names etc. and store it into an MS ACCESS database. The module is working fine in my machine and also in client machines, but some of the clients are complaining that they are getting the error at the time of running the module. They are also using MS Office Outlook 2003. They are getting the error when try to run the application.

The error is like this:

System.IO.FileNotFoundException: The specified module could not be found.

I think sometimes CLR fails to load unmanaged dll of OUTLOOK. I have tried by using most of things but till now there is no success. All the dlls are present in applications root folder.

Is there any idea?

regards
