This error is likely due to outdated video driver files on your computer. You may need administrator access to update these files.
Navigate to Device Manager and then Display Adapter to check the model and brand of video card on the computer. Then go directly to the manufacturer’s web site (ie Intel or ATI)for the latest drivers for that card. Do not use the Update Drivers option from within Device Manager as this will not work.
