I am a Mapinfo Professional user and currently I am using MapInfo professional version 15.0 with Discover 17.0. Previously, I cannot figure out how to import Google Earth KML file to Mapinfo. But after upgrading to Mapinfo Professional 15.0 bundled with Discover, I can easily import KML file to Mapinfo.
Here I will show you how to import KML file to Mapinfo Professional.
Open MapInfo and go to Discover | Import and Export | Vector Import. Next select Google KML from the list.
