No, Apple stopped supporting windows 7 a while ago. Download Windows 10 upgrade ISO (from Microsoft) since the upgrade is free and use your win 7 activation key on windows 10 (it will let you).
I'm more or less going that route. I'm preferring to stay in OS X, even for my windows needs. I have a bootcamp partition but overall there's really not much reason for me to boot out of OS X.
Running Windows in VMware is a good idea, one that did not come initially to mind 🙂
He's trying to install windows 7 and the error message is clear that he needs window 8 or higher to install, so I don't think a 64bit version of win7 will work.
