If you're like me missing some spelling language in Office2007 applications, fear no more! Office 2003 Proofing Tools work just fine. These are the procedures for installation: Enjoy!

Office 2007 – Proofing Tools
This step is necessary because Proofing Tools installation won't even start if there isn't any Office2003 application on the system
Office2007 works side-by-side with Office2003 so fear not of breaking your 2007 installation
Also, after this step don't start any Office2007 programs because it'll start reconfiguring itself to accommodate side-by-side installation with Office2003
