If you have reinstalled the original Sony Operating System, the Vaio software should be automatically reinstalled.
If you have clean installed your own version of Windows 7 then you will have lost all the Sony software. For licensing reasons this preinstalled software cannot be downloaded. Drivers are downloadable from the Vaio Support website.
I have the VPCEH2F1E and it crashed I sent it of to get fixed to the dealer I bought it from (not the Sony Store)
he told me he needed to re-install the os. When I got the laptop back all of the Sony Software like Vaio Gate which was pre-installed originally was gone. I was wondering if there would be anyway I could get this software back.
