ActiveX document question

Does anyone know what is needed to "deploy" an ActiveX document? I'm new at this and am finding little documentation.

Here's the scenario: I've created an AcX document in VB6, and used the p&d wizard and packaged it to our web server. It creates a "project1.htm" file, which shows a link to the UserDocument1.vbd file - which is the document I've created.

The document runs fine on my machine, but when I go to certain other users' pc's, and they try to select the UserDocument1.vbd link - it gives them the "Open from current location" or "Save to disk" message.......

What is it not finding so that it can run? (we've tried selecting the "Open from current location", but nothing happens). Any ideas would be greatly appreciated.

Thanks!
