What is the proper procedure for updating users to Dragon NaturallySpeaking v11 if they have a new 64bit PC?

Scenario: I have a customer running Dragon NaturallySpeaking v9. They just purchased a new computer running Windows 7 with a 64bit processor. 

Question: What’s the proper upgrading procedure?

Answer: The customer would purchase the Dragon NaturallySpeaking upgrade to version 11.  One the new PC running Windows 7 (or whatever) 64bit, they will use the Dragon NaturallySpeaking v11 upgrade installation disc.

The installation will still look for the previous installation of DNS, but as you know, previous versions will not install on the Windows 7 64bit machine. This is where the previous installation disc comes into play. You will have to insert the original installation disc to show that this is a true upgrade, and then you will be able to continue with the installation.
