Acrobat and WinWeb
Get the Acrobat software
If you do not already have Acrobat Reader or Acrobat Exchange software installed on your PC, you should first download and install the Free Acrobat Reader software for Windows, then come back here.
Modify WinWeb to recognize PDF files
After Acrobat Reader or Acrobat Exchange is installed, you will need to modify your set of Helper applications in WinWeb.
The notes here are current as of WinWeb version 1.0 Alpha 2.1
Edit the winweb.ini file with your favorite editor. In the [Launch] section you will need to add a line that reads:
Entry#=application/pdf,winvoke wingo.inv c:\acroread\acroread
Where # is a new Entry disignator.
In the [Extensions] section you will need to add a line that reads:
Entry#=.pdf,application/pdf,binary
Where # is a new Entry disignator.
You are done. Restart WinWeb. Now when you click on a link which is a PDF file, WinWeb will download that file to your default temp folder, prompt you for the name to save the file under, and automatically launch your Acrobat Reader software to open and view the file.
