Windows Vista adds an additional security measure with User Access Control (UAC). In Vista, when a user is logged in as an Administrator, it allows you to install software but if that software tries to update core files either during install or when the application runs, it may fail. By turning off User Access Control, you can eliminate that second level of security that causes error messages when trying to install the TapRooT® System Software.

NOTE: You can always turn UAC back on after the installation is complete.

1) Click on the Start Orb and above the button in the search box type in msconfig and press [Enter] on the keyboard.

Say [Yes] when prompted by User Access Control to allow this program to execute.

2) When the dialog box comes up click on the "Tools" tab, scroll down, select 'Disable UAC' as shown below, and press [Launch]

This opens a window and runs the selected command shown above. After completion, you will need to reboot before completing the TapRooT® System Software installation.
