I installed my intous3 wacom tablet and it says reinstall. i tried dowloading the new drivers from wacom, that doesnt work either. it works with my regular mouse just not the mouse and pen that came with the intous3.

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.

check the battery of the pen

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!

on some older pens, the barrel can spin out of position. If your barrel turns, it can mess up it's function.

Turn the barrel until you hear or feel a clicking into position and try again.

If that doesn't work, move wacom cable to a different usb port. worse case, replace pen.

Hey I had this problem too with my Bamboo too, I'm not sure if it was anything I changed or whatever but either way the blue light was on but it wasn't registering the pen.

I found a way just minutes ago to fix it however!

Go into 'start', 'all programs', then look for 'pen tablet'. Hopefully you should have this. If not then download the latest driver for your tablet from the wacom website and that should install it.

Next choose 'pen tablet preference file utilty'. Then under 'my preferences' choose to remove. Bingo! All was well in the world again.

This worked for me so hopefully it will for some of you guys too! Good luck!
