Cannot reinstall Sql Server Management Express

Hi,I just unistalled Sql Management Express and now I want to install it again but the installer says the product is already installed,Can somebody help me with this

What SQL components do you still show in Add/Remove Programs? Can you click on Remove and then on Report to show the detailed list and post the contents back to the thread?

Thanks,
