Brett pointed me to the latest set of rollup updates for Exchange 2007. There are quite a few new KB articles too. This one particularly caught me out last week:
Error message when you try to install Exchange Server 2007: “The image file <path>\setup.exe is valid, but is for a machine type other than the current machine”
And I’ve got a 64 bit machine too. I just started the install on the other one.
Oops. What a pillock…
