Because if you buy the download only from Intuit, you get just one download for one computer. If you buy the CD, you can install via CD on 5 computers or install via download on 5 computers. You cant, however, install via CD on one computer and download on four others. You can't mix and match the installation methods.
On the paper insert with your License Code it specifically states, "To get started, pick ONE of these install methods: CD OR Download"
So instead of installing with the CD, use the download method only and you'll get to install it on five different computers. The crazy thing is, the CD is the same price or, in most cases, cheaper than the download only price on Intuit's website 😮
