Hi Audrey

If you have Windows 7 Pro pop over to this link Virtual XP to download and install virtual XP.

If you are using a lesser or different version of Windows then you will need a genuine copy of XP to load into a virtual environment, with VMWare being a popular option.]

Microsoft Office is a totally separate program from Windows, and can be installed on any version of Windows that meet the minimum requirements. (Including standard versions of Windows)

Hope this helps

Bill
