Can't uninstall Exchange 2007 SP1 Mailbox role from Server 2008 R2

If you are getting error:
"An error occurred. The error code was 3221685466. The message was The service is already registered.."
while trying to uninstall Exchange 2007 SP1 Mailbox role from Server 2008 R2 (RC in my case)
try changing registry key value from "Uninstall" to "Install" located at
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Exchange\v8.0\Mailbox\
after that try uninstalling again.

  19. I have known my friend Jack for some years. But he applied for help to me. His MS Exchange info was crashed. Only today I could find the proper solution and sent it to him. He was greatly surprised and thanked me a lot. Moreover he presented me a gift and this tool might solve this situation likewise successfully - edb repair.

  24. Worked, for those that can't find the Key follow it but instead of just Mailbox look for \MailboxRole\ and change the Action Key to Install.
