- Turn UAC back on or switch your user account rights back to Standard.
- Switch back to the original UAC/Rights configuration that you installed ClearContext under. Uninstall ClearContext via Add/Remove Programs. Switch to the desired configuration, then reinstall v3.1.0 or greater. The installer will recognize your account settings and install ClearContext for all users, ensuring that it will run the next time you open Outlook.
If you continue to have issues, try the complete removal script and reinstall. If that doesn't work, you may need to re-enable the add-in.
