PDFs open in Adobe Acrobat Reader DC by default

[jmt356]

Today, I downloaded Adobe Acrobat Reader DC. It has taken over Adobe Acrobat Pro as the default program for opening PDFs. I have gone into Settings | Choose default apps by file type and selected Adobe Acrobat Pro as the default for PDFs. I also did the same by right-clicking a PDF | Open with | Choose Another App and selecting Adobe Acrobat Pro and ticking Always use this app to open PDFs. However, PDFs continue to open in Adobe Acrobat Reader DC by default when I open them from Windows Explorer.

In my experience, Adobe Acrobat has a mind of it's own, and will listen to no reason.

I recently started using Calibre (freeware) for other purposes, and I like it so much I'm considering using it as my default .pdf reader.

...I have gone into Settings...

Try this way:
1) Settings | Apps | Default Apps
2) At the foot of that dialog, click 'Set defaults by app'
3) Find Acrobat Pro in the list, click on it than then click 'Manage'
4) Ensure Acrobat Pro is listed for everything, if not click on it and set it.
