Adobe Acrobat Reader

PS "Adobe Acrobat Reader DC Advanced Guide" on the Windows store is described as "This app is an complete guide for Adobe Acrobat Reader. It has all essential video tutorials and tips for Adobe Reader." This is NOT Acrobat Reader !!

For info of people thinking of replying: the Windows Phone Lumia 950 XL is a discontinued phone which runs Windows 10. 

For the original responder (1) Acrobat Reader is COMPLETELY FREE; do not pay anything. (2) Do not mix it up with Adobe Acrobat, which is paid-for software. (3) Make sure you download ONLY from http://get.adobe.com/reader (4) The app store has an obsolete thing called Acrobat Reader Touch; might work better on your phone.

You'll have to provide more information if you want any help... What happens when you try to download it? From where are you downloading it? etc.
