I wouldn't bother with Adobe Acrobat Reader - it's bloated and terrible on any OS - install Okular from the Software Store - it is far superior in so many ways.

It looks ocular giving less warning messages... maybe better.

When you see the functionality of what it can do it is 100% better! It's also available for Windows 10 users in the Windows Store.

You can annotate pdfs and save as an Okular archive so all annotations are saved - choose form pinned post-it notes and in line annotations - you can even dictate the font and font size in your annotations (but not the pinned one, first option of reviews), You can add underlines to key points, add highlight colours to key points and in different colours for different key points, or draw ovals round. You can extract text, diagrams, and tables into a text document - and its FREE!

It can read comic books, jpgs, bitmaps, rtf files, xps files and pdf's. It is the most versatile document/image viewer you are ever going to need in modifying creating new documents/pdfs!

And did I mention it is a piece of junk? Actually, that is still too nice to describe it. Forced to use it on my work PC - I am convinced Acrobat has an unwritten requirement to get exponentially worse with every version iteration relative to Windows' iterations.

On Linux, Libre (I forgot which one of Libre's components) opens PDFs just fine for me. On Win7, I use Foxit.

Having to work from home I have the advantage of not having to use Windows 10 - I have to modifiy documents for students from primary to College age in modified large print and Braille and I can do it all in FerenOS. The time saved using Okular ant TextMaker 2018 is absolutely brilliant.
