Hi,
the Demo version runs under Linux only. After download, make it executable with:
chmod a+rx TmoleX-demo-591-x86_64.bin
(adapt the file name, it depends on the version that you have downloaded).
And then start it:
./TmoleX-demo-591-x86_64.bin
The rest of the installation will be done with a graphical user interface which guides you through the installation.
