Cannot uninstall MSN messenger 9 beta

Hello friends,
I am running MSN 9 beta. I cannot uninstall it. No option in add or remove program. Can anybody have any idea to uninstall it?

Thank you.

To remove WLM 9.0 beta3 use Windows Installer CleanUp Utility 1.0. Select one or more programs that were installed by Windows Installer from the Windows Installer CleanUp dialog box. To do this, select the programs that you want in the Installed Products list in the Windows Installer CleanUp dialog box. After you make this selection, the utility removes only Windows Installer configuration information that is related to those programs.

To disable the MSN 9 from startup, follow these steps:

• Right Click on My Computer
• Click on Manage
• Click plus sign for Services & Applications
• Click on Services
• Double click on Messenger in Services
• Set the Startup Type to Disabled

If you are using windows xp or vista, try following:

• Go to Start
• Click Run
• Type following in the box:
