How to fix zotfile unable to find path for pdf reader

Shabnan
I extracted the Table of Contents for a PDF using zotfile. When I click on the link for a certain section, a pop-up with this message comes up: "Unable to find path for PDF Reader. Please set path manually in hidden preferences (see zotfile documentation)"

I saw the earlier post about accessing hidden preferences via about;config. However, when I accessed the "extensions.zotfile.pdfExtraction.openPdfWin" there was no value there to start with, so deleting the string value wasn't an option.

Later, after re-setting microsoft edge as my default pdf viewer, clicking on the links didn't even bring the pop-up anymore; nothing happens, it still isn't working.

    As far as I know, there's no way to get Zotfile to open PDFs using a "modern" Windows app (i.e., the kind of app you find in the Microsoft store, and where there's no .exe file in "C:\Program Files" to launch the program). So that rules out Microsoft Edge (and my own preferred/default PDF reader, Drawboard).

    I've always had a "backup" PDF reader (I use Foxit, but Acrobat should work as well), which I use for opening PDFs from Zotfile. Interestingly, I just tested it after not using this feature for a while, and I'm finding it's not working at all for me. So there may be some other issue here as well. But again, I don't think there's a way to get it to use Edge, even when everything's working properly.

    (I'd be happy to be corrected if I'm wrong about this.)

    No, we don't believe it's possible to set a UWP app as the handler (in terms of the PDF reader setting in Zotero, but the ZotFile setting would be the same):
