Windows 7 64-bit

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.

1. Navigate to the folder that contains the setup.exe file for your Acrobat 8 installation.
2. Locate the file "data1.cab" and open it (this may require a third party compression utility, such as WinZip).
3. Inside the content listings, locate the file "adobepdf.dll_64" and copy it to your desktop.
4. 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 file extension.
