I don't know why this error occurs...on my system I can execute the executable.
Which windows version have you?

Anyways in the documentation there is a big red text in the Exporting section with the notice: exporting not available in demo version!




This has nothing to do with the error. It is just a feature that is available in the full version which is not published yet.

But I couldn't extract the file from that website.




The file is a WinRar-Zip-file and you should be able to extract it with WinZip or WinRar.

So now I tried this demo, but nothing really works?




Well...the GUI Editor is stil in development. However the application should start and you should be able to configure the panel which will be shown. It is probably a bit confusing because of the little documentation.
I will try to make a video of this soon.
