I currently have X1 Producer Expanded on this 32 bit computer - From my Sonar accounts product list I can download it again into a new computer that will be a 64 bit. Do I need to upgrade X1 in some way to have it operate within the 64 bit environment or will it just recognize and do that during installation? Thanks

The installer contains both 32bit and 64bit versions. There is an option at the beginning of the installation process to select which version to install. Don't forget to grab the updates from the support page http://www.cakewalk.com/S.../By-Product/SONAR%20X1

You will just download the X1 Expanded installer and at the point you install it will ask which one to install. Its if I recall a check box. 

Good deal - thanks for the reminder about the updates...
