Configuring your web browser to automatically open Adobe Acrobat Reader
Generally, you will need to locate your browser's preferences section and enter the Acrobat Reader's executable file path. You may also be required to enter a file extension identifier in the "File Extension" box; if so, enter PDF.
It appears configuring Internet Explorer 4.0 and above to launch the Adobe Reader is not necessary.
If you receive a blank browser screen when using Netscape please read this additional information.
