When you install an Acrobat product on a system that includes a browser, you automatically configure the browser to open PDF files within the browser window. Acrobat installs ActiveX plug-in files that allow you to use IE or AOL to open PDF files. If Acrobat is installed, but PDF files don't open in the browser window, work through the following steps to configure the browser:
1. Make sure that the system meets the requirements for the Acrobat product you use. For a list of system requirements, refer to the following resources:
-- Acrobat 6.0 Professional: See the Adobe website at www.adobe.com/products/acrobatpro/systemreqs.html .
-- Acrobat 6.0 Standard: See the Adobe website at www.adobe.com/products/acrobatstd/systemreqs.html .
-- Adobe Reader 6.0: See the Adobe website at www.adobe.com/products/acrobat/acrrsystemreqs.html .
-- Acrobat 5.x or Acrobat Reader 5.x: See the ReadMe file included with the application.
2. Make sure that the ActiveX plug-in is in the correct location:
-- Acrobat 6.0: Program Files/Adobe/Acrobat 6.0/Acrobat/ActiveX folder
-- Adobe Reader 6.0: Program Files/Adobe/Acrobat 6.0/Reader/ActiveX folder
-- Acrobat 5.x: Program Files/Adobe/Acrobat 5.0/Acrobat/ActiveX folder
-- Adobe Reader 5.x: Program Files/Adobe/Acrobat 5.0 /Reader/ActiveX folder
3. Use a supported version of the browser:
-- Acrobat 6.0 and Adobe Reader 6.0 support IE 5.1-6.1 and AOL 6.0-8.0.
-- Acrobat 5.0 and Acrobat Reader 5.0 support IE 4.0-5.0 and AOL 6.x (Windows 2000, Me, 98, or 95) or AOL 5.x (Windows NT).
4. Restart Windows to make sure that IE or AOL is accessing the most current Windows registry information.
5 . Reinstall Acrobat or Acrobat Reader to make sure that the correct plug-in information is added to the Windows registry.
Ed. - If you are using Firefox, you may need to download and install a Firefox plugin. Also, check the "Tools -> Options -> Download -> View and Edit Actions" list to make sure that PDF is listed to open with Adobe Reader. |
