Uninstalling MySQL
Is anyone here familiar with uninstalling mysql via NSIS?
I looked through the windows registry for some hint as to where the mysql uninstaller will be generally located but I didn't find it. Any freshly baked ideas that you can cook up with be greatly appreciated and ravenously digested!

Hey guys, i figured out how to detect and uninstall MySQL.
I used orca to get the GUID of the MySQL installer msi.

Then I wrote the following code to uninstall it.

  ; Uninstall MySQL
  services::GetServiceNameFromDisplayName 'MySQL'
  ; $0 contains the # of services found that have the name MySQL.
  pop $0
  ; Stop the MySQL service from running if it exists.
  ${If} $0 > 0
        messagebox mb_yesno "Would you like to uninstall MySQL server?" idno dont_uninstall_mysql
        push 'MySQL'
        push 'stop'
        services::SendServiceCommand
        Pop $0
        Messagebox MB_OK "$0"
        ; Uninstall MySQL 5.0.51a
        ExecWait 'MsiExec.exe /X{3EAB224E-12F7-4EBA-AC0A-A2B10FEEA0E4}' $0
        ;StrCmp $0 'Ok' success 0
        dont_uninstall_mysql:
  ${EndIf}
