I travel for work as well. One of the posters above hit the nail on the head. When companies speak of monitoring, it is allmost 100% internet usage via a proxy and email monitoring. I doubt your company would go as far as monitoring the applications you install and your usage while away from the office.

If you want to feel a little more safe, install the program under a renamed folder, dont use desktop or start menu shortcuts and just browse/open the executable. Most likely you dont need to take these steps but if it makes you feel a little safer, there is no harm.
