I downlaoded Eric's polygon exporter DLL from Formatting coordinates with DmsFormat, linking to weather data, three new utilities - MP2K Update Archives - MP2K Magazine (http://www.mp2kmag.com/update/?id=5). When I try loading into MapPoint 2011, I get a COM Add-in not trusted error.

I can load the Spacial Data Import COM Add-in from Miscrosoft with no problem.

The ultimate goal is to export a Drivetime zone as an ArcView compatible file. Does anyone know the best workaround for getting MapPoint to trust the custom Spacial Data Import/Export DLL?

Update. I installed MapPoint 2011 on a Windows XP machine vs. what had originally been one running Windows Vista, and the Spacial Data Import Add-In with export script loaded just fine into the program and works perfectly. In the end, it must have been a security related feature in Vista that prevented me from running the Add-In.
