>I have developed a application that allows EMAIL to be sent to the INTERNET. This application works fine on the DEVELOPMENT PC (WIN/NT) but when I place this under the USER PC, I get the following prompt, OCX LOCATION. I believe it is looking for MSMAPI*.OCX but I have not determined how this gets under the WINDOWS/SYSTEM directory. Can anyone help me with this.

You should have a robot running this OCX not all the PCs that runs your application. In that way, you don't have to worry about that. :)
