Hi again! Yes you assumed correctly in your 1st statement. We are currently discussing the usefullness of the password following your replies. As for the downloaded file it should be, by default, in your download folder. At the extract step, you are able to chose where you place it on your computer. Inside the file should be an executable with it's own specific icon.
We are still new to all this and your feedback is of great help. If you need any other help, or would like to help us help you by providing screenshots , you can always join us on our discord. It would be our pleasure to asssit you and figure out how to make this as user friendly as possible.
