Hi there, I try to install Exchange 2007 SP1 on a Windows 2003 R2 64bit SP2 (German MUI) The installer tells me to install KB928368 for the Mailbox Function. But when I try to install that update, the update tells me that a newer update is already installed. So what to do??? Thanx a lot Sirhexalot

Hi Try to update your machine before installing SP1, and check. Regards

Same error. I cannot install that update, because a newer update is already installed. Should I try to uninstall SP2 for Windows 2003 ???

if u uninstall SP2 from Windows Server so u'll not be able to install Exchange SP1, but maybe u can uninstall SP2 and then reinstall it again, but I'm not sure about this solution. Regards

I try to uninstall, and then reinstall SP2. Thanxs a lot

Hi, I think that you should firstly install Microsoft .NET Framework SP1, if didn't help you install KB942027. Regards

Hi there,i reinstalled SP2. That helped. Thanx a lot.
