This article explains which Windows touch driver should be used for Windows devices

Recommendations for Windows driver support can be found below.

First, see if touch works without a driver (make sure the USB touch cable is connected if using an external computer).  
If it does, then you don't need a driver.
If it does not or if it is not properly aligned, download the latest Windows multi-touch driver.
It should work for most Elo products, including single-touch products.
