"The driver being installed not validated....obtain from manufacturer."

In attempting to update my video cards on my Latitude D610, Mobile Intel® 915GM /GMS,910GML Express Chipset, for the service pack win2k_xp142550 from (http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&ProductID=1862&DwnldID=12539&strOSs=44&OSFullName=Windows*%20XP%20Professional&lang=eng)

I recieve the message listed in the title, "The driver being installed is not validated for this computer. Please obtain the appropriate driver from the computer's manufacturer"" 

Cause?
