I have windowq vista business 32 bits and a graphics card "Mobile Intel 4 Series Express Chipset Family".
Its driver was released the september 2008, so I want to upgrade it thanks to the intel website (http://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Graphics&ProductLine=Laptop+graphics+controllers&ProductProduct=Mobile+Intel%c2%ae+4+Series+Express+Chipset+Family).
I tried the two last drivers but I received a message "The driver is not validated for this computer" and the installation stops.
Somebody has an idea???
The solutions is to uninstall the intel media acceleration program. Then, there is no more error message when installing the intel driver.
