First off all: Mapsource is an outdated program since 2010!
You should use BaseCamp/MapInstall for current maps.
I guess your problems, because your previous MapSource version was probably very old (older than v6.15.11).
I recommend to clean your system from all Garmin installations:
- uninstall MapSource (and possibly all other Garmin programs)
- delete registry path
- Code:
HKEY_LOCAL_MACHINE\SOFTWARE\Garmin\
and - Code:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Garmin\
- if you need MapSource really, reinstall v6.16.3 - all gmap versions of Garmin maps in following path will be shown:
- Code:
C:\ProgramData\GARMIN\Maps
- reinstall all Family versions of Garmin maps in Windows registry. If no setup or batch file available, use MapSetToolKit for installation of this maps.
