Wacom Mouse XC-100-03 Right click doesn't work

I would uninstall the drivers, reboot, and let your OS install the mouse. Then try to re-install the new drivers that were released by Wacom yesterday available at the link I provided. (You probably got them there, I don't know)
If it goes 'wonky' again, uninstall the new drivers and use the older ones provided on the website or just let you OS install if it will.

The first thing you have to do is upgrade your Windows from version 8.0 to 8.1. Version 8.0 just has too many bugs plus it shouldn't automatically update anymore Check this MS page out.

Install the latest Windows 8 1 Update Windows Help


Here are the bare bones manual installation steps from the page:
Install the update manually

Make sure your PC is plugged in and connected to the Internet using a non-metered connection. Don't disconnect, unplug, or turn off your PC while the update is being installed.

Swipe in from the right edge of the screen, tap
Settings, and then tap Change PC settings.
(If you're using a mouse, point to the lower-right
corner of the screen, move the mouse pointer up,
click Settings, and then click Change PC
settings.)

Tap or click Update and recovery, and then tap or click
Windows Update.

Tap or click Check now.

If updates are found, tap or click View details.

In the list of updates, select the update containing
KB 2919355, and then tap or click Install.

If you're prompted for an administrator password or
confirmation, enter the password or provide
confirmation.

After the installation is complete, restart your PC and
sign in.

Note: If you don't see KB 2919355 in the list of available updates, you might be missing one or more required updates. Follow the previous steps to check for updates, install all important updates, particularly KB 2919442, restart your PC, and then check for KB 2919355 again.

Once you successfully update to Windows 8.1 we can tackle your Wacom products. There have been plenty of documented problems getting the Wacom Intuos Drivers working in Windows 8.x. Just google on "Wacom Intuos Driver Windows 8.1"

First get the latest Intuos driver version from the Wacom website.

I couldn't find any separate drivers for the Wacom mouse

Im need to the driver

Not really, but there should be screws underneath the unit to unscrew and it clips apart.

The winning answer came courtesy of Mr Benedikt Schmitt of Wacom Europe, who offered the following solution: from the Windows Device Manager, disable the “Wacom Virtual Hid Driver” device. (Go to Control Panel > System and Maintenance > Device Manager, find the driver, right-click it and choose “Disable”.) One reboot later (welcome to Windows-land, circa 2008?), everything works as desired. Pressure and tilt sensitivity inside Photoshop still work, and the pen functions just fine in the rest of the Windows desktop. The absolute mapping makes it an absolute pleasure to point quickly and precisely. It makes my laser mouse feel rather clumsy navigating a large 24′ screen!

I know this question was asked a long time ago, but I just had this similar problem and found a solution to it.

1. Install the latest Wacom drivers for your device
2. Open the Wacom Tablet Properties from the Start menu.
3. Click on the Mouse tool
4. Click on the Mapping tab halfway down the screen
5. Change the mode from Mouse to Pen

Try using a thin pair of tweezers to remove the paper. Hope this helps. Bud

I sassume you have the tablet on which the mouse sits, right? The name of the model should be written on the back of that. Just follow this link and choose your tablet model and away you go!

I had the same problem with my Intuos3 on Vista. Tech support suggested the following.

Do this.....Go to Start--->control panel---->system(in classic view)---->device manager--->click on "human interface devices"--->then click on "Wacom virtual HID driver" and right click on that and disable it. Your computer will ask you to restart and you will want to do that.

Everything works fine now.

Since you are running Windows Vista on your PC this is the driver you should have downloaded.

Serial cables are not hot swappable. The computer and tablet should be turned off before you plug them in.
