For Vista, you will have to disable UAC temporarily. Go to -> Control Panel -> User Accounts -> Turn User Account Control On or Off -> Then uncheck the box. No need to restart. Try to install. It will say "Platform not supported". When you close the dialog a Windows Dialog will pop up and say something about correct settings (maybe it turns XP compatibility on?). Click "Retry install". It should work now.
Solution: Download the 4.97-6 driver (http:// www.wacom. com/productsupp ort/download. cfm?id= 161&product= CTE4)
Uninstall newer tablet driver.
Install normally in Windows XP.
