That works as normal. Edge is opening the PDF as it should.

After trying your suggestions, I'll post on Mixcraft's forum with a link back to this trhead and ask them to have a closer look at what's really happening behind that Help menu command.

I deleted that key, but the problem remained. But then I found that the parent folder to those keys (".pdf") had the same setting! (the "MoI.PDFFile.1" value). So I deleted that value as well, and there it was! Now Mixcraft Help file opens with Edge again as before. Thank you for your assistance!

Hi Rolf, that's great I'm glad it is solved.
As best as I can tell it seems to be a bug in Mixcraft where it must be going through
the registry with its own custom code to find a program to launch under the .pdf file
type.
That's not advisable because it can end up launching a program other than the one
that the OS shell has set as the default handler.
The solution is to call the OS ShellExecute() function instead, passing in the path to
the help .pdf file.
