Enable touch on HP 2740p with Windows 8.1

After upgrading my HP 2740p from Windows 8 to Windows 8.1 I lost touch.  The Wacom pen input still worked.  I re-installed PenTablet_533-3.exe and Wacom Digitizer Driver 3.0.7.24 – sp52863.exe (in that order) but touch wasn’t restored.

It wasn’t until I opened Window’s Control Panel, searched for Touch, launch the Touch Settings app, and run through the 16-point calibration was touch restored.

Touch Settings v3.0.7-24

Touch Settings (WTouchCPL.exe) on my system is installed to C:\Program Files\WTouch
