You MUST unzip/EXTRACT all the files into a directory somewhere, NOT RUN INSTALL, select the VGA adapter in device manager, go into the properties page and the drivers tab, there will be an option there to update the driver. Clicking this takes you into a wizard which gives you two options 1) Search for a suitable driver or 2) Display a list of known drivers. Go with number 2 and select have disk ... then point the browser to the directory where you extracted the files. When it has found the directory it should show you the driver. Select it and click OK. At some stage it will probably ask you if you are sure you want to install the driver as it has not been digitally signed by microsoft, and warn you that it may not work properly. Just click ok to continue installing and when it has finished, reboot.
