Uninstalling FSX

Tried to remove FSX using the Control Panel\Add-Remove program but after the Install Shield progess bar reach about half way, the uninstall quits. Any any other proper way of removing the FSX from the drive? will formatting the drive erase the software. there is not much in that drive except FSX and Program Files. I intend to use the drive to load FSX DeLuxe in another more powerful PC.
