There was an error opening this document.

Report · May 23, 2018

When I preview my email attached PDF file I can read it
properly. However, when I download this PDF file into my PC I have the
following error and cannot open the file at all: "There was an error
opening this document. This file is damaged and could not be repaired". I am
using Adobe Acrobat Reader DC product with windows 10. May I get help on this?

Hi Woo youngk,

Could you try following troubleshooting steps:

1- Reboot the machine if you haven't already and try opening pdf file again and check if that helps.

2- If that doesn't work, check if an update is available for Reader using "Check for updates" option under "Help" menu, reboot the machine after installing update and try again. You may also download updates from here: Adobe - Adobe Reader : For Windows

3- If that doesn't work, try disabling mode and check if that helps. Click Edit > Preferences > Security ( Enhanced ) > uncheck the box next to Enable protected mode at startup. Visit this link for more info: Protected Mode troubleshooting | Adobe Reader

Note: Disabling protected mode is for troubleshooting purpose only, enable protected mode when troubleshooting is complete.

Let us know if you need any help.
