10.8.5 Mountain Lion BootCamp Windows 7

I recently replaced the hard disk in my iMac (Early 2013 21.5"). Reloaded Mac OS 10.8.5, and now I am trying to install Windows 7 with BootCamp.

However, Windows 7 refuses to install from the USB drive that BootCamp Assistant created. If I install manually from my Windows 7 DVD and then try to run Boot Camp "setup.exe" in Windows 7 I am greeted with a message that this version of BootCamp won't work on this computer.

I was able to install the old BootCamp drivers I saved from 3 years ago when I first installed Windows 7. Everything seemed to work OK with that, Ethernet, video card, etc. except no USB.

I have followed Apple's instructions very carefully: Install Windows 7 and earlier on your Mac using Boot Camp - Apple Support

It does not seem to work.

I cannot make sense of the whole mess. Same computer, same hardware, same software, and it worked a couple years ago. Is the setup program checking the current Mac OS version on the Mac partition from within Windows and then refusing to run?

iMac, OS X Mountain Lion (10.8.5), Early 2013 21.5" iMac

Can you verify the iMac year/model? Please see Identify your iMac - Apple Support as a reference.

Yes, I downloaded the version 5.1.5640 that was recommended by Apple, and replaced it according to step 11.

The old version, actually in a folder named "Windows Support" is version 4.1.4586. This was the version that I had saved from 3 years ago when I first installed.

Looks like there is a bit of confusion, "About This Mac" lists mine as a Late 2012.

The tables list both Late 2012 models and early 2013 models, which I am pretty sure are the same. No major changes where made to the iMac until late 2013. I'll give the 4.1.4586 version a go.

I think Apple needs to clean up their compatibility tables, there are obviously conflicts.

http://www.everymac.com/ultimate-mac-lookup/?search_keywords=2544 indicates that you have a 21.5-in Late 2012 iMac with a model identifier of iMac 13,1. Is that correct?
