Issue: "The file AdobePDF.dll is needed" error is encountered when you install CS3 on 64-bit Windows
When you try to install Adobe Creative Suite 3 on a 64-bit version of Windows, the installer returns the following error message: "The file AdobePDF.dll on Windows Vista CD-ROM is needed."
You are given the option to browse to the file.
Manually extract the file "adobepdf.dll_64" from the data1.cab file before installing Acrobat. When the prompt appears, navigate to this file and select it.
Run the installer setup.exe and when the prompt appears, choose browse and select the file you copied to the desktop.
Note: If the file cannot be selected, change the file type drown down in the dialog box to "Files of All Types." Or, rename the file to "adobepdf.dll" by removing "_64" from the end of the filename extension.
Adobe Acrobat 8 Professional is installed with the Design Premium, Design Standard, and Web Premium versions of Creative Suite 3. Although Adobe has tested Adobe Acrobat 8 (Standard and Professional) on Microsoft Windows 64-bit operating systems running on a 64-bit processor machine, there are known limitations.
As the Adobe PDF printer is not supported on 64-bit operating systems, the 64-bit version of the AdobePDF.dll does not get extracted during installation. Therefore, the installer can't locate it. While Acrobat is installed, the Adobe PDF printer isn't installed. Following the update procedure above addresses the issue.
