can't use Microsoft Equation

[Guest]

I can't run my Microsoft Equation in Microsoft Word. Every time I try to
insert this object or I click on the equation that are found in other files,
it always return error.

It asked me to repair, but after it loads something that seems repairing, it
returns the same error screen again. A alert said I did not install it
properly.

I delete Office 2003 and reinstall it, the same thing happened. I don't know
why, can anyone help me?
