Thank you for this reply.
Unfortunately, I have not been able to install it! I downloaded it from the site you mention. It comes as a .msi file. When I try to extract it with 7zip, I get a large number of files, but no .exe file to install it! I tried to click on the icons, and I get the message "This application cannot be installed on your PC" (Windows 10 / 64 bits)
Any suggestion? Sorry, but I am far from being a smart geek, and I need instructions.
