NOTE: For Vista, User AccountControl (UAC) should be turned off for users who do not have administrator control. If you do not have administrator level control, the plug-in will not install or run properly with Vista UAC controls on. You will need to turn UAC off. To access UAC settings, go to Control Panel > User Account and Family Safety > User Accounts > Turn User Account Control on or off. For users running Photoshop as administrator, the plug-in will install and run properly with UAC on.
