Welcome to the Board!
#1 - If you already have Office installed, then you can goto Control Panel-->Uninstall a Program-->Click on Office-->Change/Repair.
When the Wizard comes up you'll walk through some steps as to what elements you want to change. When you see Excel, expand the folder and make sure that each one is checked as being included on the local computer.
Once you get that done you should be able to find what you're after.
