Something must have changed if you can no longer run something that used to work 
Try the last combination of VMWare, OS X, Xcode and CoronaSDK that worked for you. If that doesn’t work then something you aren’t aware of must have changed (like a Windows update). If it does, try with the latest version of CoronaSDK. We haven’t changed anything that I know of that would affect things like this.
I assume you can build just fine using CoronaSDK installed natively on Windows 7 or you would have mentioned it.
Don’t think I can downgrade back to 10.11.2 without skipping iOS 10 as that is needed by my clients.
