Can not set Acrobat reader as a default to open PDF files

[Guest]

Somehow , I can not set Acrobat Reader DC as a default for my PDf files  in Windows 10.

Even if I right click on a PDF file and select properties, it will not show Acrobat Reader DC as an option.  

I do have the program installed and I tried to open it, but it will not open. 

Please help

Right-click a PDF file and select Open With - Choose Default Program. Then select Reader from the list of applications and tick the box that says to make it the default program for that file type.
