Problem
When using Internet Explorer to open a PDF document you receieve the following error:
Adobe Acrobat does not support Internet Explorer's Enhanced Protection Mode (EPM). Either install the latest version of Adobe Reader or disable EPM in Internet Explorer.
If you want to open a PDF document only for reading, without having to wait for all the plug-ins to load, or having to move the plug-in files, you can temporarily disable the plug-ins in Acrobat. Press the Shift key while double-clicking the PDF file you want to open. Adobe Acrobat does not load any of the plug-ins while opening the document. PDF Won't Load or Pull Up brandonp54430164. New Here, Feb 21, 2017. Copy link to clipboard. I have recently downloaded Adobe Reader, because it is necessary.
Make sure that the PDF includes interactive, or fillable, form fields. Sometimes form creators forget to convert their PDFs to interactive forms, or they intentionally design a form you can only fill in by hand. If you can't type in the form fields, then the fields are probably not interactive.
Solution
This issue is generally caused when an older version of Adobe Acrobat (the PDF creating software) is installed.
Because the version of Adobe Acrobat is older, it does not support the EPM security feature in Internet Explorer 10 and later.
Solution 1 – update Adobe Acrobat

Update the version of Adobe Acrobat.
Update the version of Adobe Acrobat.
If it is a moderately modern version of Acrobat the update will hopefully include support for Internet Explorer's EPM security feature.
Solution 2 – disable opening PDF files in the browser
This solution involves changing the Adobe Acrobat settings so that the PDF files do not open in the browser window.
Depending on your browser the PDFs made automatically open in their own window or the download option may appear.
- Open Adobe Acrobat
- Click on the ‘Edit' menu then ‘Preferences'
- Click on ‘Internet' on the side bar
- Under ‘Web Browser Options' untick ‘Display PDF in browser'
- Click ‘OK' to save the changes.

Solution 3 – use Adobe Reader as your default PDF software
The solution to to make sure the latest version of Adobe Reader is installed and then set Adobe Reader to be the default program for PDF files. This way when you open PDF files from Internet Explorer, the latest version of Adobe Reader will handle the file – which supports the EPM security feature.
To set Adobe Reader as the default program you will need administrator rights on the computer. The steps below show how to do this:
- Open Adobe Reader
- Click on the ‘Edit' menu then ‘Preferences'
- Click on ‘General' on the side bar
- Click on the button ‘Select Default PDF Handler'.
- Click on the drop down box and select ‘Adobe Reader …'
- Click on ‘Apply' and then ‘OK' to exit out the dialogs
- PDF files will now open in Internet Explorer, using Adobe Reader.
When trying to view e-journal articles or files on Blackboard Learn, or from other sources, some files may open inside a browser window but display as a blank, or grey space, or the file may not finish downloading. Try right-clicking the link to the file and open it in another tab or another application like Adobe Acrobat DC Reader.
There are several other remedies to try listed below...
1. Open Adobe Reader, go to Edit > Preferences > Internet and either tick, or untick, 'Display PDF in browser'. Then close down Adobe Reader so that the setting change takes effect.
Try to open the file again. Depending on your new setting the PDF should open, either inside the browser or, if you selected Open PDF outside the browser, a new Adobe Reader window should open, this time outside the browser with all the content displayed.
2. Alternatively, use a different browser. Firefox is available from the Start menu > All Programs > Central Software folder > Browsers folder > Firefox 24.0 (or later versions). Firefox may report that the Adobe Reader plug-in needs updating - just click on the grey icon to open the PDF. If you still encounter a problem you can also fix it by choosing Tools > Options > Applications tab > look for a drop down for Adobe Reader (or Adobe Acrobat) which should be switched to 'Use Adobe Acrobat in Firefox'. Refreshing the page will change the behaviour to read the PDF inside the browser frame.
3. If you still have a problem opening a PDF please also try changing your connection speed setting: open Adobe Reader, go to Edit > Preferences > Internet and under 'Internet Options' change the connection speed from 56 Kbps to 112 Kbps.
4. Another thing to try, in Internet Explorer, is to add the host site to the Trusted sites policy, go to Tools > Internet Options > Security tab > Trusted sites (green tick) > Trusted sites button > add the host to the zone, for example *.ingentaconnect.com > click on Add button and Close and OK (server verification is not required). This should permit the download to go ahead next time you download a file from the host.We have done so for Ingenta - see the link to a separate FAQ on this.
5. Look also for pop-up alerts near the top of the browser and enable the pop-up if you trust the site - the publishers' sites that we link to may be trusted as they are known to us. Once the pop-up is enabled, it may open automatically, or you may need to refresh the page you were on.

6. If you see an error message: 'Acrobat failed to connect to a DDE server' open Adobe Reader and select Edit > Preference > General, and uncheck 'Enable Protected Mode'.

[This answer applies to Adobe Reader versions 9 and X. For Adobe Reader XI it is different: the settings must be changed in IE8 (or IE9). Please note: the default setting on campus is to open PDF files outside the IE8 browser. Note also, on campus, Adobe Reader X opens a PDFaloud alert in a separate pop up box - you should OK this or the PDF may not download successfully.]
