But if you go to the "Downloads" tab and select any "Windows 7" operating system, all you get is a download for "VAIO Update version 22.214.171.12440".
I guess (I don't own a Vaio), you're supposed to download and install this utility, and then it will discover and install all the necessary drivers.
However, if you select for example "Microsoft Windows Vista Business 32-bit" operating system, and then select "Original driver", you get a list with "Camera.EXE" on it...
So if the update utility doesn't work, you can try to install the Vista driver, in compatibility mode, if necessary.
