I've been forlornly trying to install Windows 10 on an Apple Mac Pro (using Boot Camp). The Mac Pro is currently running OS-X Mojave. To give you some background... Mojave (for whatever reason) won't install anything earlier than Windows 10 - but it can't install Windows 10 either (because the latest Win10 ISO file is larger than 4GB). So after years of sniping at Windows for having a 4GB file limit, it seems that Boot Camp in fact has a 4GB limit also!!

Does anyone know if there's a Win10 ISO file anywhere that's smaller than 4GB?? Even if it's an earlier version, I'm assuming I could install it and then upgrade Win10 later to the current version.
