Narrative:

As we were being vectored for approach; we received an 'anti-ice duct' warning message. The appropriate checklist was called for and completed. The checklist led us to turn off wing anti-ice and close 14th stage bleed valves; thus rendering all anti-ice protection inoperative. The checklist then states to leave icing conditions. Once the checklist was completed; the warning was no longer present. At the time we were in icing conditions at 3000 feet but not accreting ice. We had just descended through rime icing from 8000 to 4000 feet. Given the proximity to the airport and minimal time to landing; we determined the safest course of action was to continue the approach and land rather than go back up through the known icing conditions. We elected to not declare an emergency and landed without incident.
