The roaming profile is placed on a computer that is accessible by all of the computers that are running Dragon. I have installed my roaming file on the AC server, since all of my computers access that server. Nuance recommends that you install Dragon on the computer that has the shared roaming file, only for the simple reason that it is much easier to run the acoustic tuning on the file if you have dragon installed on the same computer. For me, that wasn't a good option. However, the file can be copied to one of your computers that is running Dragon, then the tuning can be performed and then the file can be copied back into the original shared directory. Dragon allows you to install the program on 4 computers. If you need additional installations (which I did, for my office computer), the additional instillation is $99. Whenever you remove dragon from a computer to transfer to another computer, make sure that you uninstall it using Windows uninstall in the control panel. Also make sure that you have an Internet connection at the time that you uninstall, so that way the Nuance server is notified that you have uninstalled the program. Then when you reinstall it, you still have an installation credit that you can use.
