GSX Pro trial - how to install?

[Copper]

I'd really like to recommend friends to try GSX since it has a trial mode for certain airports according to the manual (KSFO, EDDM, LIMC and the FSDG airports).
But apparently there is no way to install it without a license since the Installer/Updater itself doesn't offer MSFS products.

How is this supposed to work to do a trial before buying? Is it mandatory to have at least one of the FSDG sceneries to try GSX or would it be possible on the three airports - if so, how to install GSX Pro?

This has been discussed and answered in several other threads:

So, in general, the ability to install the program without a license, is reserved to users of any FSDT airports, because GSX is free to use there, so we needed a way for those users to install without a GSX Pro key, and in this configuration, the program will work on additional 3 Trial airports.
