It is important to distinguish between the old v8.5 and the latest v8.5a. Version 8.5a is XP compatible and also works on Vista. The old version 8.5 from Sierra is not XP compatible so is unlikely to be Vista compatible either. You should therefore consider upgrading to v8.5a. We have v8.5a in stock.
