Demo version

Demo version of GPMAW.

The current demo version is identical to version 12.20, released on November. 2019.


Press the above link to download the file ‘gpmawDemo.exe’, which upon execution will install GPMAW on your computer.

The installation is essentially a full install of the program, however, as the license file is missing, the program starts by asking you for a license number. If you do not provide a number, the program starts in Demo mode, and closes down after 10 minutes. A timer in the title bar shows the remaining time.

You can contact Lighthouse data for a demo license. This is valid for 4 weeks and requires that the program has access to the Internet during startup.

The manual for GPMAW 12.20 is part of the installation, but can also be downloaded here.
