Did you read this from MSDN?

It walks you thru distributing the MapPoint Control run-time with your VB6 app. The "Create an installation disc for an application created using the MapPoint Control" is the important part, if you already have the right number of end user licenses. I've just tested it on one machine and it seems to work, plus you can modify the autorun.inf, so that the installation of the MapPoint Control is not displayed, so the enduser only sees your app installing.
I believe if you do the minimum installation from a network drive and a full copy of the 2nd "Run" CD is in the same location, the app will call the info from there. So you only have to install CD1 and the control will run the "Run" CD from the network when needed, same as if it were in your CD drive. I inadvertently found that out from a removable drive, but I didnt test it fully, as that wasnt my goal.
Hope that helps,
