Materialize how to install

I am very lost as to what the Bounding Box Software website is referring to when it says, “Extract the Materialize zip somewhere it does not need special permission to write its temp files (not in ProgramFiles).” I do not know which one is the Materialize zip file and where I am supposed to put it. I have attached an image of the files that have been downloaded from the Bounding Box Software website. If you have any suggestions for how to install Materialize, please let me know.

You can extract it on desktop or download folder.

Thank you! This helped.
