To all those having problems, sorry I wasn't keeping an eye on this forum.
Device manger -> Monitors -> double click current monitor -> driver tab -> update driver -> Browse My Computer -> Let Me Pick From a List of Device Drivers on my computer -> click the HAVE DISK button : point it to where you extracted the driver zip from the attachment above.
It is an unsigned driver of course, so you have to tell it to 'use it anyway'.
It does work, I just installed it on a brand new win7 pro x64 install, I only found this thread had new replies as I was hunting about to see if there was an official win7 driver now.
I still can't believe just about every iiyama monitor ever built has a driver built into win7 except this one
