Troubleshooting Problems with Viewing PDF Files
If you have problems viewing PDF files on this (or any) Web
site, they may be the result of known bugs in your PDF viewing
software. It is recommended that you try upgrading to the latest
version of that software.
Some users have encountered problems with using Adobe Reader
as a Web browser plug-in. If you want to remove Reader as a plug-in,
while still keeping it on your system as a stand-alone application
-- or if you are not currently using Reader as a plug-in, but
want to begin doing so -- then you need to change Reader's Display
PDF in browser setting. To change this setting in Adobe
Reader version 7.x, follow these steps.
- Close all Web browser windows.
- Start Adobe Reader.
- Open the Edit menu, then click Preferences.
- Click on the Internet category.
- To configure Reader as a plug-in, mark the Display
PDF in browser checkbox. To configure it as a stand-alone
application, clear that checkbox.
- Click OK.
- Exit Adobe Reader.
- Restart your Web browser. Confirm your configuration change
by browsing to a PDF document.
Another potential solution to problems with viewing PDF files
in your browser is to save the PDF document to your hard disk
or local network before opening it with Reader. To do this, right-click
(Windows) or hold Control and click (MacOS)
on the link to the PDF, then choose the option to save the target
of the link. Choose a location on your disk or network in which
to save the file, then open the file from that location.
