Excel no longer opens but says 'preparing to install'

I have had excel working for a few years but suddenly I am having problems. I have tried to open up an excel document and then just to open up excel, but I am getting the message 'preparing to install'.

After a while it says 'this update package could not be opened. verify that the update package exists and that you can access it, or contact the applicaiton vendor to verify that this is a valid windows installer update package'.

I did find the sheet I was hoping to access by going to the start menu, typing 'run' and then typing 'excel /'. Then tried re-copying it to the desktop or a disk. But when I try and open those, I get the same installing message error.

found the solution - not the repair, unfortunately, but i remembered that i had to deactivate User Account Control - don't ask why, but it works.  It must have been reactivated with some automatically installed update, once i went into control panel, user accounts and deactivated, it fixed the problem.
