1. Download the latest MapSource from Garmin.
2. When finished downloading, if you use archiving software such as 7-Zip, WinRAR or PowerArchiver,
you can right click on the file that you downloaded and extract. If you’re unsure,
you can use Universal Extractor to extract the MapSource installation file.

The extracted files can also be found in the Windows Temp folder if you know how to get there
because some folders in the Temp path are hidden. Run the installer and when you see the Welcome
screen go to the Temp folder. Look for a folder with 7zxxx.tmp (the x’s are random characters) for a name which
contains a file called MSmain.msi inside with several other files. Copy that whole folder to your chosen location.
3. Open the extracted MapSource folder . You should see a number of files and folders.
Now run MSmain.msi first, wait for it to complete (there will be no windows to click on)
and then run Setup.exe. Follow the instructions to complete the installation.
