All the drivers compatible with Live! webcams are listed on the Support page of Creative. Visit the page and scroll down to the last section (webcams). Those are the only devices that have Windows 7, 8, and 8.1 compatibility. Alternatively, download the driver for Windows XP and manually install the webcam by pointing the Windows Driver installer window to the folder (usually Program Files\Creative Webcam Live!). Select the INF file manually and with a bit of luck it will work.
You can update the driver from the Device Manager (Start > Run > devmgmt.msc)
