I have downloaded the setup for Wondows 11, but when I try to install it, I get an error message

The message says - Application cannot be started.  Contact the application vendor.  When I click on the "Details" button, I get a wall of text that I don't understand.

Thanks for replying.  How do I do that>  I know enough about computers to be dangerous.  LOL

Right click on the install program, a pull down menu should appear.  Select Run as Administrator

It worked!  Thank you so much!  I have been screwing with this for days.  I should have asked sooner!

HI, yes that is the workaround for now while we are looking into why it is suddenly required. Thanks.
