Error : Previous MapSource not found! Setup will terminate. Installation of MapSource in to your system

All sounds good and I actually found a link to download the latest MapSource from Garmin’s official website. When I tried to install, I got the error message:

Previous MapSource not found! Setup will terminate.

It seems like the file that I downloaded is an update and not the full installation setup. Luckily there is a trick on how to install MapSource without having the original installation CD.

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.

If you do not have any maps installed for MapSource, you might see an error window that says “MapSource could not find any installed MapSource map products. Please install one or more MapSource map products and start MapSource again”. There are some maps for MapSource that cost money and some free
