I am developing in VB.Net. I learned on an app that we built that uses Mappoint. At the time, I had Mappoint 2002 on my machine. I then (foolishly thinking it had value) purchased Mappoint 2004 and installed it over 2002. Once the facts became evident, I uninstalled 04, returned it, and re-installed 02. However, my registry is all messed up and it thinks I still have Mappoint Control 11.0 (02 is 9.0) and other 04 components when I don't. Now the app won't run.

Anyone out there that can help?

Reinstall the OS, dummy.

Delete the key from CurrentUser\\Software\\Microsoft\\MapPoint

The format of the key might not be quite right, but the hierarchy is (I just messed with it earlier this week).
