If you are using NT 4.0 and install IE 5.5 without installing IE 4.0
previously, you will get the following error message: 
       
       IE4 or higher needed.

AS-5 needs the components that are installed with IE4 or it won't operate 
properly on the NT platform, hence the error message. 
You can download IE4 from the Microsoft Web site:
