My tablet initially shipped with Windows 8. The touchscreen worked fine under Win 8. After upgrading to Windows 10 however, the touchscreen no longer responds to finger touches and gestures.

I have updated to BIOS A16 and every other firmware/driver update I could find.
Everything works great under Windows 10 except for the touchscreen in tablet-only mode.

I read online that updating the panel touch driver will fix my issue.

In updating the panel touch driver, I do run into the error message problems listed here:

www.dell.com/.../EN

The specific error message I receive is: "Unable to locate a Synaptics Touch Controller. Verify if the device is properly installed on the system."

None of the solution options listed in the above knowledge base article work in my case.

My dilemma is when I have everything undocked, I cannot use the touch screen to "click" the installer's dialog buttons on the screen with my finger (since the touchscreen is what's not responsive and what I am trying to fix).

I have tried using a simple USB cable-connected keyboard and USB cable-connected mouse to just the tablet (undocked from the dock or travel keyboard). No luck... same error message.

I have confirmed that no I2C Device has an exclamation point by it. Just to be sure, I disabled and re-enabled the device and tried the firmware update again... no luck.

I have confirmed that I am installing firmware update v1.0.5.100 from the file SynaUtilitySfx_v1.0.5.100.exe.

Any help very much appreciated!
