Simply unpack a mapsource update (see links above), run MAIN.msi and then rename mapsource.exe to something else. Mapsource_6.13.6.exe and then copy it into your main Garmin Mapsource installation folder (usually c:/garmin).

Oct 2012 by tympg As MapSource will not install if it does not detect an existing MapSource in the PC, many MfM members get stuck trying to install MapSource for the first time.

The following three installation methods are known ways of circumventing this problem. Method 1 • Download and install Garmin's into your PC. • Download and run the latest installation file (should be named like '). • Follow the on-screen instructions, and MapSource should be installed on your PC. • If you already have maps installed, you can view your map by going to View > Switch to Product >, otherwise you can now proceed to into MapSource. Method 2 • Download the latest installation file (should be named like '). • Use or to open and extract the contents of the EXE file you downloaded.

(See Note: Portuguese UI) • From the extracted files, run MSmain.msi (newer MapSource) or Main.msi (older MapSource). • Run Setup.exe located in the same folder. • Follow the on-screen instructions, and MapSource should be installed on your PC. • If you already have maps installed, you can view your map by going to View > Switch to Product >, otherwise you can now proceed to into MapSource. Method 3 • Use one of these registry files: • For 32-bit Windows. Mapsource64.zip Unzip and run the REG file. • Download and run the latest installation file (should be named like ').

• Follow the on-screen instructions, and MapSource should be installed on your PC. • If you already have maps installed, you can view your map by going to View > Switch to Product >, otherwise you can now proceed to into MapSource. Notes • For subsequent MapSource installations (i.e.

You already have MapSource installed), just download and run the latest installation file (steps 2-4 in Methods 1 & 3). • There is also a suggestion of creating a dummy 'MapSource.exe' in the MapSource directory (see post below). This flat-out does not work -- I've tried. • If a message ' There is a problem with the MapSource registry. Please re-install MapSource and start MapSource again' appears, download and run to clean up the registry. This is an old problem and hasn't been happening lately.
