MSN Messenger Not uninstalling

I tried MSN Messenger 1.0 and i can’t uninstall it.
Operating system: Windows 7
Computer Model: Emachines E732ZG

since older msn is less annoying with uninstalling, try going to c:/program files (x86) or just program files if your running 32 bit windows, and deleting the msn messenger service folder

do you tried to run uninstaller as adminitrator?
