I have been using Calibre on my Windows 10 machine for a few years with no issues. When there is a book I want to read it would automatically open up in the Calibre Reader.

I just install the Calibre 64bit e-book program on this new pc running windows 11 pro and was finally able to figure out how to move my library to this new pc.
I wanted to read a book today and it opened up, but the book is opening in Adobe Acrobat instead of the Calibre e-book viewer.

How do I get the books in my library to open in then calibre e-book viewer (and just leave other .pdf files on my computer to open with Adobe Acrobat or whatever .pdf program I choose to use in the future?

Thank You.
