Thank you for the update Paul.
I am sorry to say, but you cannot run that version of Microsoft Office in Vista.
You will have to upgrade to Windows 7, if you wish to use that on your computer.
Another option is to use a better & free version of Office, called "Open Office". You can install Open Office on your computer with no issues.
You can download a free version of Office called Open Office from the following link: http://download.openoffice.org/
- Download, save, and run that file
You can use that program to create and edit Office documents (Word, Excel, Powerpoint).
I look forward to your next message or your rating below.
