Can I run the software from a USB stick or external drive?
Basically that is possible, but you will have to keep a few things in mind. Certain settings such as column widths, screen size etc are placed in the registry of Windows. So if you start on a different computer, these will not be present there. The license information is also placed in the registry, so when you move to an other computer, you will have to re activate the software. Be sure to have the license information with you in that case.
