If you literally take the expression “no installation required”, you expect the program to start doing things once you have clicked the download button on the website! Because the download was a ZIP file, you at least need to unzip the contents, which I did. Both Chrome and my AVG believed that it MIGHT be a virus, but in order to run whatever it was, I over-rid those. Then Windows 10 did not believe an .exe could be safe, so I over-rid that, LOL. Cautious is fine, as long as it doesn’t block innocent. “Innocent until PROVEN guilty”, right, even in the world of computer software? It’s a real laugh, that in order to run these good programs, you have NO antivirus running, with a connection to the internet…
