Bootcamp will not recognise x64 Windows 7 ISO or Install Disc

27" iMac late 2012

I've tried using both my Windows 7 ISO to create a bootable drive, and also attempted using a disc burnt using disc utility, but I keep encountering the following message with Bootcamp. My Windows 7 install disc is a mixed x32 and x64 (I would obviously choose x64 bit when running windows install later) But is displaying the following image?

I used the same windows disc to install the x64 bit version on my 2011 27" with no problems, I've also tried to use another Windows 7 install disc but it's giving the same error...

"Boot Camp only supports 64-bit Windows installation on this platform. Please use a ISO file for 64-bit Windows installation."

Any ideas how I could fix this?

iMac, OS X Mountain Lion (10.8.2)
