I found these instructions posted on several different websites but I really doubt there exists Windows 7 x64 drivers. You might want to give it a try:
• 1st You download this Webcam Driver.
• Intel Pro PC Camera CS430 Personal Web Camera for Driver
• After this, install the Webcam driver in the system.
• Install Instructions:
• Installation of Webcam Driver
• Go to the control panel
• Click on the System Icon
• Click on the Hardware Tab
• Click on the Device Manager then
• Select the Unknown Device or printer device where yellow Question Marks sign on it.
• Right click on it and uninstall it.
• After this go to the top of the device manager and click on scan for hardware changes.
• Driver installation Wizard start.
• Brows Your Driver from the Hard Disk and click on next.
• Driver will auto-install.
