Solution 4: Use Another PDF Reader
If this problem still remains, then you should try using another PDF reader. We recommend using the Adobe Acrobat reader as we have found it to be the most useful and user-friendly application.
Solution 5: Check If The PDF File Is Corrupted
If using another PDF reader also doesn’t work, then most likely the PDF itself is corrupted. Try opening a different PDF on your computer. If the PDF opens without causing any problem, then definitely the other PDF is corrupted, which is why you are unable to open it.
If the document is important, then contact the person you got it from and ask for another copy. Also, ask them to check the file before sending it so that you don’t end up with another corrupted PDF.
