Playing on flashdrive?

Does anyone know if you can load civ iv onto a flashdrive, and then play the game off of the flash drive? The reason I ask, at work, I only have a workstation and can not load any new product. Would be nice to be able to play at lunch, and when goofing off.
Thanks.

Not possible.

Thanks, I did not think it would, but thought I would ask before trying.

Boot the workstation from the flash drive rather than its hard drive, then install civ on the flash drive. You will need a pretty big flash drive, though.
