We have already discussed about many errors regarding PDF files, like: recovery, password protection, converting files to other formats, etc. Today I am going to explain about the most common errors of PDF files when tried to open. You may have already seen these types of errors before.


Sometimes, you must have faced problems with a PDF file which doesn’t open with Adobe Reader in Windows OS, but some files can be opened. Below, I have described some of the most common errors while opening PDF files on Windows OS:

1. “There was an error opening this document. Access denied”

Symptom: The error, mostly comes in Adobe Reader v10.1. The issue was fixed in the v10.1.


Resolution: This error was resolved in v10.1 and the current version is 11. The best solution to resolve this error is to update Adobe Reader.


Step by Step Solution:

I. Open Adobe Acrobat Reader XI
II. Go to Edit >> Preferences…
III. Click on “Security (Enhanced)” on the Left side panel
IV. Uncheck “Enable Enhanced Security”
V. Click Yes in the prompted dialog box
VI. Then click OK to save the changes and exit Adobe Acrobat XI.

2. “The Adobe Acrobat/Reader that is running cannot be used to view PDF files in a web browser”

Issue: Sometimes you may have seen the following error message "The Adobe Acrobat/Reader that is running cannot be used to view PDF files in a web browser. Adobe Acrobat or Reader version 8 / 9 is required. Please exit and try again." while viewing a PDF file in a browser.


Reason: This error can appear when the folder, which contains Adobe Reader or Adobe Acrobat, or one of its folder or sub-folder has been; renamed or moved, or Adobe Acrobat or Reader has otherwise become confused which exact application to use as a helping application within the browser.
