Hi Einscan-S
Thank you for the change log.
I looked at the .pdf for the install, and "Get licence from local" is not quite correct... you cannot move the .ple file to the local set up unless you create the folder yourself when you download and extract the install application.
If your computer opens the downloaded software directly, then the install process will fail.
All it needs at the licence options, is a "Browse" function like you see when installing drivers that come on a preloaded CD, that way you can point the software to your licence aka .ple file in your system.... otherwise create a folder in the initial install process, and ask people to move their .ple file into this with another splash screen.

Ideally the software should auto update, just a 2¢ reaction
