I have a Windows 7 x64 Enterprise running on ESXi 5.1. I'm trying to upgrade the VM to Windows 8 Enterprise.
From what I've read on the TechNet website I need to upgrade to Windows 8 first, and then Windows 8.1. I'm using the ISO image I downloaded from Microsoft Volume Licensing website and during the setup I get an error "Windows cannot find the Microsoft Software License Terms. Make sure the installation sources are valid and restart the installation."
What do I need to do to get the upgrade working?
