Hi, I was just reading my assignment (PDF) for class. I highlighted the text and made comments. When I tried saving the file, I got an error saying that the file cannot be saved because it's for reading only. Next thing I know, all the texts disappeared. I still have my highlights and comments although they are meaningless because I don't know which part of the text these comments are referring to.
I tried the following method but didn't work:
Preferences >> Documents >> Uncheck "Save as optimizes for Fast Web View."
I don't even know where this PDF is located... the PDF file I found has no highlight or comment on it (I probably downloaded the same document twice). I need this document for my assignment tomorrow (Tuesday), so please help.
We are sorry for the trouble. As described you are not able to save the document and getting the error document could not be saved the file may be read only.
Would you mind sharing the version of the Adobe Acrobat Reader you are using? To check the version go to Help > About Adobe Acrobat and make sure you have the latest version 20.12.20043 installed. Go to Help > Check for Updates.
If the file is stored on a shared network/drive please download it to your computer locally and then try to edit and save and check if that makes any difference.
For testing purposes: Please try to turn of the protected mode and see if that helps. Go to Adobe Acrobat Reader > Preferences > Enhanced Security > un-check 'Enable protected mode at startup', disable the protected mode and un-check 'Enhanced Security ' > Click OK and reboot the computer.
Note: Turning off the security may possess security risk, please turn on the security after testing.
