win7 embedded x64 TouchScreen controller

Hello I have two win7 x64 PC's and monitor with touch screen.
monitor is located near one PC (1), but HDMI is connected using a long cable to the another (2).
PC's are connected to the LAN
So I want to use LAN connection instead of using long USB cable for touch screen controller.
I has tryed to install server at the 1 PC and client at the 2 PC
I have a problem, when trying to use touch at the 2 PC
Error using device.
How can I solve this problem?
PS when I trying to use mouse physically connected to the 1 PC at the 2 PC - everything is seems good.

Win7 is not supported anymore sorry. It is "as-is" if it doesnt work its not getting fixed.
