InstallThe correct course of action, of course, will be to first install SP1 HR1 so environmentenvironments are consistent - this will likely be the instructions from Support without having to add further hotfixes to complicate the setup (remembering that hotfixes are not supported in the context of being used with other hotfixes etc. but are provided on an 'as is' basis.
I've checked the list of hotfixes applied in HR1 and nothing seems to explicitly match the scenario described but that's not to say it isn't the solution.
