Installing Office 2003 on Vista OS

Hello,

I am trying to download Office 2003 Standard Edition onto my new laptop with a Vista OS. I have a license for the software and I downloaded Office 2003 Service Pack 3. But I continue to get an error message as soon as I attempt to run the program that says:
“Settings fil E:\FILES\SETUP\SETUP.INI is missing or invalid”
Can anyone offer any solutions to this problem?

Thanks!
