Error: Could not connect to MapInfo Pro COM Interface


I previously had a old version of Discover installed on the computer, and have upgraded.

Every time I start MapInfo Discover I receive an error message "Error: Could not connect to Mapinfo Pro COM Interface." or "This utility must be started inside MapInfo Discover"


This issue is usually resolved by opening a command prompt (search the start menu for this and open it), and then typing in -
"C:\Program Files\MapInfo\Professional\MapInfoPro.exe" -regserver

And hit return.

If this doesn't work, uninstall both MapInfo Pro and Discover, and reinstall the Discover bundle.

1) Delete (or backup to a separate folder) the contents of -

2) Go to your start menu and search for "Regedit" and open this tool. 
3) Navigate in the Registry Editor to -

4) Right click on this Key name (Encom) and delete this.
