Go to Start orb-->Right click computer-->select properties-->on the left near the top click device manager-->you should see your hardware device either by connection type (USB, Firewire,ETC.) or in it's own category--> right click your device -->select properties--> select rollback driver. Now you can attempt your update again but this time right click the downloaded .exe file--> select properties--> select the compatibility tab-->check the box that says run in compatibility mode--> select for windows vista service pack 2 and then run the installer. Should this still fail rollback the driver again and try a different compatibility mode.
