Problem Reinstalling Office

[arts714]

When I try to open Microsoft Office, I get the following message: "Microsoft
Office has not been installed for the current user. Please run setup to
install the applications."

I downloaded the 60 day trial version from the Microsoft website so I don't
have a disk. How can I "run setup to install the applications.?"

I have been using the program successfully for the last two or three weeks.
I experienced this problem after uninstalling Quicken 2007 to deal with
another unrelated problem.

Thanks.
