Dorico SE does not start

I have Dorico SE 4 and the license to run it, but every time I try to run the application and sounds installers, it fails in JavaScript because “the directory name is invalid”. What do I do about this?

Welcome to the forum, @Noel_Teter. Could you attach a screenshot of the actual error message you’re seeing?

Hi Daniel,
I updated my computer to Windows 11 and was able to load Dorico; however, even though I have HALion Sonic SE open and running, no sound will play. Do I need to connect it to an output, and if so, how?
