If you got a new computer today, that is what "he" would do and everything would work with CbB just like it does now.
 
Although I would use the Command Center. Copy the installers into its download directory, install and activate. The Command Center checks its download directory before trying to download the files.

To answer the initial question... so that you don't have to use two computers to use both programs.
 
Kind regards,
