MS Office 2003 and Vista OS

I own the software for MS Office 2003 and it is loaded on my PC (I work from home). I now have purchased a Toshiba laptop which came installed with Vista OS. Will my version of MS Office run on Vista OS without difficulty? Do I have permission to load it on my laptop since both machines are mine and I work alone from my home?
