Adobe Acrobat 4.x and later and Adobe Acrobat Reader 4.x and later include ActiveX plug-in files for Windows NT 4.0, Windows Me, Windows 2000, Windows 98, and Windows 95. (Acrobat 4.x and Acrobat Reader 4.x do not support Windows Me.)

The ActiveX plug-in files enable Microsoft Internet Explorer and America Online (AOL) Web browsers to display PDF files in the browser window using Acrobat or Acrobat Reader. Internet Explorer and the AOL browser display PDF files in the browser window automatically if the ActiveX plug-in files are installed.

Acrobat 4.x later and Acrobat Reader 4.x and later are compatible with Internet Explorer 4.x or later. Acrobat 5.0 and Acrobat Reader 5.0 support AOL 5.x in Windows NT, and they support AOL 6.x in Windows Me, Windows 2000, Windows 98, or Windows 95. Acrobat 4.x does not support AOL.

Installing the Acrobat Plug-in Files
The plug-in files install automatically with Acrobat and Acrobat Reader:

• Acrobat 5.0 - The Acrobat 5.0 installer automatically installs the plug-in files Pdf.ocx, AcroIEHelper.ocx, and Pdf.tlb to the Program Files/Adobe/Acrobat 5.0/Acrobat/ActiveX folder. The Acrobat Reader 5.0 installer automatically installs the plug-in files Pdf.ocx, AcroIEHelper.ocx, and Pdf.tlb to the Program Files/Adobe/Acrobat 5.0/Reader/ActiveX folder.
• Acrobat 4.x - The Acrobat 4.x installer automatically installs the plug-in files Pdf.ocx and Pdf.tlb to the Program Files/Adobe/Acrobat 4.0/Acrobat/ActiveX folder. The Acrobat Reader 4.x installer automatically installs the plug-in files Pdf.ocx and Pdf.tlb to the Program Files/Adobe/Acrobat 4.0/Reader/ActiveX folder.

If you select a PDF file and the browser prompts you to save the file to disk or to open it outside the browser window, or if the browser doesn't respond, do one or more of the following:

Disclaimer: If these suggestions do not enable you to view PDF files the way you prefer, refer to the browser documentation or contact Microsoft or AOL.

• If you use Acrobat 4.x or Acrobat Reader 4.x , make sure that a Pdf.ocx file and a Pdf.tlb file are in the Program Files/Adobe/Acrobat 4.0/Acrobat/ActiveX folder or the Program Files/Adobe/Acrobat 4.0/Reader/ActiveX folder.
• Reinstall Acrobat or Acrobat Reader to make sure that the correct plug-in information is added to the Windows registry.
• Restart Windows to make sure that Internet Explorer or AOL is accessing the most current Windows registry information.

Enabling the Browser to Use Acrobat as a Helper Application
If you'd rather have PDF files appear in a separate Acrobat window, you can enable the browser to use Acrobat or Acrobat Reader as a helper application. Internet Explorer or AOL then starts Acrobat or Acrobat Reader, which displays PDF files within an Acrobat window instead of within the browser window.

To configure Acrobat or Acrobat Reader as a helper application:
1. Exit from Internet Explorer or AOL.
2. Start Acrobat or Acrobat Reader.
3. Choose Edit > Preferences > General (Acrobat 5.0 or Acrobat Reader 5.0) or choose File > Preferences > General (Acrobat 4.x or Acrobat Reader 4.x).
4. In the Options section, deselect Display PDF in Browser (Acrobat 5.0 or Acrobat Reader 5.0) or deselect Web Browser Integration (Acrobat 4.x or Acrobat Reader 4.x).
5. Click OK, and then exit from Acrobat or Acrobat Reader.
6. Restart Internet Explorer or AOL.

Note: The next time you select a link to a PDF file in Internet Explorer and AOL, a dialog box will prompt you to specify what to do with the file. If you select "Open this file from its current location," Internet Explorer and AOL open the PDF file in Acrobat 4.0 or later or Acrobat Reader 4.0 or later as a helper application. If you select "Save this file to disk," Internet Explorer saves the PDF file to your hard disk, from where you can open it later.

For more information about the general preferences in Acrobat or Acrobat Reader, refer to the online Acrobat guide.

Downloading a PDF File to Your Hard Drive
You can download PDF files to your hard drive from a Web page's link, and then copy text in the file, distribute the file, or save the file to a disk.

To download a PDF file from a link:
1. Right-click the link to a PDF file, and then choose Save Target As from the pop-up menu.
2. In the Save As dialog box, select a location on your hard drive, and then click Save.
