I believe you can download it from lilliput's website. www.lilliput.com.cn I haven't tried it myself but I saw the dl there.
I'm running Windows XP, and I have the latest drivers for the Lilliput as downloaded from the Egalax web site. The touch screen works fine and I have the Touchkit calibration tool, but how do I right-click? Some of the reviews I've read indicate that there is a tray applet that provides a switch from left and right clicking. I don't seem to have that - anyone know where I can get it?
If the driver Touch kit utility is installed it put a little tool down in your desktop tray. You click on that and a tool will pop up allowing you to specify that you want the next tap of the touch screen to be a right click instead of the normal left click.
