[@DouglasH] Windows defender does not block it here… it may be your windows defender settings trying to protect you from anything downloaded from the internet… or you may have cloud based opinion detection enabled … I refuse to enable that as I know better than the vast majority of people on what is genuinely dangerous and what is not than people who are not educated admins. You could try right clicking on the downloaded executable and selecting unblock on the general tab or you could deselect the only allow installs from Microsoft app store or disable the windows 11 block on installing unsigned installers… as many good programs still do not sign their installers as it costs money to sign executables… This installer is NOT digitally signed and will have issues installing under default windows 11 settings.
