A couple of things to look at:

Was the .exe simply copied over to the new machine by the user and they said it did not work?

Did the user install the application using your published installer?

I have to ask because I have seen where users will simply copy the executable over to a new machine not understanding that the dependency files need to be loaded and registered on the new machine. The installer will do this.

The 0x80040154 error means "Class not registered". So, there's a component that your code is using that isn't installed on the Server 20080 box. Perhaps the correct version of Office isn't installed on that box, if you're using Office Interop?
