--- Comment #4 from Hans Leidekker hans@meelstraat.net 2010-05-29 13:41:00 --- On current Wine a custom action called UndoDisableSqlAgent fails because of a missing registry key: HKEY_LOCAL_MACHINE\Software\Microsoft\MSSQLServer\SQLServerAgent
It should probably have been created earlier by the installer. Adding the key by hand gets it to the next problem, a custom action called ConfigServer failing because EnumDependentServicesW is a stub.
