Yes, you can install Avaire over existing tile. Make sure the existing tile is flat and firmly attached. If there are any high-spots, you'll need to knock them down. Or if any low areas, fill with a self-leveling compound.
If you are installing above existing tile, you will be adding roughly 9/16th of an inch to the floor height. Make sure to check clearance for doors and cabinets.
