Tutorial
You cannot open preferences for Adobe from within Internet Explorer or Netscape, so please exit any PDFs you are reviewing before following these instructions. We don't have Macintosh or Unix versions of Acrobat Reader, but are willing to post instructions for those versions.

1. Open Adobe Acrobat Reader or Professional and go to edit from the menu bar. (Skip to step #3 by using Control+K)

2. Click on Preferences.

3. Click on Internet from the list box.

4. Uncheck "Display PDF in Browser"

5. Click on OK to close preferences.

Now when you open a PDF it will open in an Adobe Application Window and not the browser.
