You Need Microsoft WebView2 Runtime to Use Tuto Projector

( If you have Windows 10/11 WebView2 Runtime is normally installed natively With Edge !
But if you need it because your version is obsolete or You didn't have EDGE instaled on Windows 7 / 8
The setup of the projector will ask you if you want instal or update it , click yes !
if you are suspicious :-) the link below go to WebView2 Runtime page on Microsoft site ! )
