Install a new webcam driver in Vista with Service Pack 2 HP recommends that you download and install Windows Vista Service Pack 2 to fully utilize the updated software and drivers that it provides. You should also install the latest BIOS from HP. Microsoft provides an automated Windows update function that examines your computer and installs the appropriate drivers and programs for Service Pack 2.

• If you have not updated to SP2, take the time to do it now. You can visit the http://www.microsoft.com web site for complete information.

SOLUTION:
Remove unneeded and conflicting drivers If you have previously installed the latest Windows Vista Service Pack, or have installed additional webcam software, you may have added webcam drivers that conflict with the correct driver. To check if there are additional drivers installed and to delete the conflicting drivers, do the following:

1. Click Start , type Device Manager , and select Device Manager from the list provided.
2. Click the plus sign (+) to expand the list of webcam Imaging Devices option.
   • If the Microsoft webcam driver is the only driver listed, go to Update the webcam driver .

   • If there are no webcam driver, or after you have uninstalled all of the drivers, go to Reinstall the original webcam drivers .

Reinstall the original webcam drivers If the webcam driver is not listed in the Device Manager window, or you have removed all the imaging devices drivers, do the following activities to install the original webcam drivers using the HP System Recovery.
