  5. Delete the ION Enterprise folder

  6. Scroll down to Microsoft > MSSQLServer (still in HKEY_LOCAL_MACHINE\SOFTWARE)
  7. Right-click and rename MSSQLServer to something different
    i.e.: MSSQLServerOld
  8. In Windows Explorer, navigate to the C:\. Find MSDEsetup.log in the right-hand side of the window and either rename or delete it.
