After installing MapInfo Pro, my custom Projections are deleted


After upgrading the MapInfo Professional version, all custom MapInfo Professional projections have be deleted.


If you have installed with the Discover Bundle, it includes a backup of the PRJ file, before the MapInfo Pro installer deletes it.

At the conclusion of the updating process a copy of the previous MapInfo Projection
 file is now placed in the User's Temp folder or in my recent versions, the Encom folder -




The same backup process will also need to be applied to the Encom.prj file.

It is best practice to not simply copy and paste the entire contents of the saved projection file over the top of the newly installed projection file, as any new projections added by MapInfo Professional, such as GDA 2020, will be deleted.
Instead, openthe file in Notepad. Locate your custom projection lines (usually at bottom or top) within the 'MapInfow_backup.prj', and copy these manually into the new MapInfow.prj file located in your MapInfo Professional Program directory.
