I'm trying to find out whether Fim 2010 CM will work on Windows 2008R2 Datacenter Edition, see the TechNet information on supported Opereating Systems below, it mentions Windows 2008 Datacnter but not 2008R2. Would anybody be able to confirn if it will install and work on 2008R2 datacenter In the TechNet article the Operating System requirements states: FIM CM is supported when installed on servers running Windows Server 2008 Enterprise Edition 64-bit or Datacenter Edition 64-bit or Windows Server 2008 R2 Enterprise. FIM CM is not supported on 32-bit versions of Windows Server 2008 Regards Darren
