If you are using a newer Wacom Tablet, the service you are looking for will be called “Wacom Professional Service” and NOT “TabletServicesWacom” – If you STILL cannot find it, it may be called ”
Touch Keyboard and Handwriting Panel Service” So, if you cannot find one, try searching for the other. Thanks to Ricky Curtin for the update!
Go to your start menu and open it, type Services.exe and click the Services.exe option that will appear in your start menu.
In Services.exe scroll down until you see TabletServicesWacom, and right click that beast.
