office to dvd??

Anyone tell me, I want to download office2007. Will I be able to put it on DVD and later put it back on hard drive (should I decide to reformat)???
If so, how can I do it - I’m a noob!!

Once you download the install package, there’s no reason you can’t burn it to CD, DVD, Server location, Jump drive or anywhere else it fits. You can reinstall from this file whenever you need to. Reactivation will be a whole different situation, though. That’ll depend on M$.
