download previously purchased software

I purchased Adobe Acrobat X Standard on my old laptop a few years back and it has been great.  Unfortunately, my old lap bit the dust a few days ago and I am trying to figure out how to download this product on my new laptop.  I signed in to my account here at Adobe and can see the product is registered and can see my serial number.  Does anyone know how I can use this info to download this software onto my new laptop?
