A "plug-in" is a hardware or software module that adds a specific feature or service to a larger system. For example, there are a number of plug-ins for the Netscape Navigator browser that enable it to display different types of audio or video messages.
We suggest that you configure your Adobe Acrobat Reader as a plug-in application for your Internet browser.
Automatic Installation
If you have an Internet browser installed on your system at the time that you install Adobe Acrobat, it should automatically install itself as a helper application in the browser.
You will know that Adobe Acrobat is properly installed as a helper application if you can view the PDF file in the browser window, with a single row of special Acrobat buttons along the top of the viewing screen.
Manual Installation
If Acrobat does not install itself automatically as a helper application for your Web browser, you can also do this manually by copying the appropriate file to your browser's Plug-in folder.
Microsoft Windows
To manually install the Web browser plug-in:
- Open File Manager or Windows Explorer.
- Locate the Acrobat\Reader\Browser folder.
- Copy the NPPDF32.dll or NPPDF16.dll file to your Web browser's Plug-In folder.
Apple Macintosh
To install the Web browser plug-in, open the Web Browser Plug-in folder within the Adobe Acrobat folder.
