Hi, I'm trying to install Windows Movie Maker from the standard install page and it's giving me no errors, except this:

I already know I deleted it about a month ago because I didn't think I'd need to use it, yet it still says it's installed on my computer (Windows 7 HP Pavilion). To prove it, I ran a search through the entire computer and it didn't pop up.

It's not in my Programs list, either. So I know it's gone but I don't know why Windows is still giving me this message. It's not installed. So... my question is basically how can I re-install it? Did I do something wrong?Thank you.
