If you're struggling to find one, I have a MSDN Windows 7 64-bit ISO that I could burn and send to you. It's a legal one so you couldn't install without a key, but it might have the bits you need?
I've download /two/ Win7 x64 ISOs, and both of them have been fucked about with so much by the script-kiddy cunts that uploaded them that you can't access the fucking recovery tools. Whatever boot option you choose from the F8 menu it automatically goes into the installer at the choose which disk/partition to install on.
I've worked there. Make sure you build the hotel inside it. And the underground conference rooms. And La Grande Arche. And the bit round the back where I'd sneak off for a cigarette.
