It almost worked but then failed. I used "have disk" and chose the individual drivers (I had to do one by one to see which would work) but it then installed the drivers and Device Manager showed the ELAN touchpad  in place of the one I had, and it still didn't work. When I went to try and update the driver to the second INF file, it then realized I didn't have the ELAN touchpad, and it went back to showing my 12C HID Device with a warning sign.

It opens a CMD window and seems to install, but then nothing happens. I will reboot to see if anything changes and will edit this post with the results.

 

UPDATE: Reboot still finds the touchpad not working. Opening device manager shows the same old situation.

I guess that nothing happens, since it is "packed" for Windows 11.

 

Try again ...

 

(1) Start windows <device manager>

(2) Locate touchpad/I2C device

(3) Uninstall device

(4) Use windows explorer to enter directory containing the INF files

(5) Right click and choose install for each file:

- ETD.INF

- ETDHCF.inf

- PTPFilter.inf

(6) Reboot and check windows <device manager> and touchpad
