Unable to open Dorico after 4.1 update

Hi @jawmusic , normally we ask people to do Help > Create Diagnostics Report, but that makes no sense in your case, because you can’t even launch Dorico. Instead please execute the attached batch file and post the zip file that it creates. So please download it, unzip and then execute. The created zip file can be found on your Desktop. Thanks
