This is only an issue (usually) if you are trying to install the dedicated BaseCamp version of the map on Windows 10, via running the “install.bat”. If so, you may see the following alert:

To allow it to run, first click on the “More Info” link on the SmartScreen page.

You should now have an option on the SmartScreen to “Run Anyway“, if so, then click on that, As shown below and the “install.bat” file run just fine.

Please ensure that you are right-clicking on that file, and selected the “Run as Administrator” option, otherwise the registry keys will not get inserted and the map will not work.
