For the QB Desktop program:
Basically you just take the installer CD/file and install it on the next machine and make the appropriate selections from the prompts. If you dont have the original installer you can download it (if its still a 'current program)
But - you need to be very clear on what you are trying to achieve:
Are you just setting it up so you (single user) have an alternate workstation?
or are you moving from a single user setup to a simultaneous multi-user setup?
Either way both locations have to be on the same LAN - but the setup steps are slightly different.
and you must have the original license key regardless
