I have a Vmware ESX 3.01 server and just tried installing the Exchange 2007 Volume License version and it DOESN'T work! I built an win2k3 x64 VM from scratch and when you run the setup.exe you immediately get script errors and are unable to run the Step 4. Install Exchange portion.
I've updated my server with vmware patches as well as MS patches, and I think MS put some code in the initial javascript Setup.exe package to check for virtual machines. Other .exe and .msi files do not work either.
Anyone had the same experience? (I'm hoping not!)
