Compare old and new Garmin compatible maps

I saved an installable .exe map of Thailand from the Lambertus site back in 2013. Now I would like to install that map on my computer so I can see the changes we’ve made since 2013 in Basecamp. But when I try to install the old version the installer wants to remove my current installation before proceeding.

Is there a workaround for this situation?



You could try Javawa GMTK
Rename the mapname and change the ID so that the uninstaller cannot remove it and you can install another map.

Thank you,

I’ve used Javawa GMTK many times but not in this exact way. The installer didn’t ask about uninstalling at all - it just went ahead and did its job. It worked perfectly.
