Adobe PDF "Security Error" or Similar

Security Errors with Acrobat

When trying to open a document from a place like Microsoft Access and you see a message that says something like "Adobe Acrobat does not allow connection to [a website]," it's usually because Adobe is set to block access to that website (example: www.tru.univ). Here's how to change that setting to fix the problem:

  1. Open Adobe Acrobat and go to the 'Edit' menu in the top right hand corner of the window, then choose 'Preferences'.

  2. On the list to the left, find and click on 'Trust Manager'.

  3. Now, look for an option that says 'Internet Access from PDF Files outside the web browser' and click the 'Change Settings...' button below it.

  4. In the list that appears, find the name of the website or network you're having trouble with (it might look like www.tru.univ) and click on it and hit the 'Delete' button to remove it from the list.

  5. To add it back, choose 'Allow' so it won't be blocked anymore (example: www.tru.univ - Always Allow).


If you still can't open your document, you might need to change another setting:

  1. Still in 'Preferences', look for 'Security (Enhanced)' settings.

  2. Here, you can add specific folders to a safe list by clicking the 'Add Folder Path' button.

  3. Choose the folder path you would like to add (example: C:\Users\jsmith\Downloads) and click the 'OK' button to add the folder you have selected.

  4. You should now be able to open the file within that folder you set.
