Have a look at the default programs from Tools &gt;&nbsp;Internet Options &gt;&nbsp;Programs &gt;&nbsp;Set Programs &gt;&nbsp;Set your Default Programs and see if you can set v9 as the default for PDF.

My CEO's computer is running XP64 with IE8. &nbsp;He has had Acrobat 6 for years and uses it to quickly scan documents into PDF.<br />
<br />
However he also has Adobe Reader 9 to view newer PDFs that require a newer version.<br />
<br />
In the Control Panel, all PDFs are defaulted to use Reader 9.4. &nbsp;<br />
<br />
In the IE8 Add-Ons, all things Acrobat 6 are disabled. &nbsp;<br />
<br />
There are no Acrobat related items in the msconfig startup.<br />
<br />
However, if we click on a PDF in his browser, we get this message, followed by Acrobat 6 opening: <br />
<br />
&quot;Adobe PDF Document<br />
<br />
The Adobe Acrobat/Reader that is running can not be used to view PDF files in a Web Browser. &nbsp;Adobe Acrobat/Reader version 8 or 9 is required. &nbsp;Please exit and try again.&quot;<br />
<br />
How can I tell IE8 to use Adobe Reader 9? &nbsp;We really don't want to uninstall Acrobat 6 because he uses it to scan to PDF quite frequently. &nbsp;

browser defaults PDF links to Acrobat 6, how do I set it to use Acrobat Reader 9?

Web browsers are applications used primarily to display documents, files and media from the Internet, identified by a Uniform Resource Identifier (URI) that can be a page, image, video or other file. Some browsers require the use of add-ons or extensions to safely render the information they receive; others have systems built into them to perform the same functions.

Adobe Acrobat is a family of application software and Web services developed by Adobe Systems to view, create, manipulate, print and manage files in Portable Document Format (PDF). The family comprises Acrobat Reader (formerly Adobe Reader), Acrobat (formerly Acrobat Exchange) and Acrobat.com. The commercial proprietary Acrobat, available for Microsoft Windows and OS X only, can also create, edit, convert, digitally sign, encrypt, export and publish PDF files.
