A family of Microsoft relational database management systems designed for ease of use.

That is exactly what is accomplished by my VM suggestion.
Sorry, I beg to differ.
Yes using a VM allows what appears to be this sort of installation, but it is not a simple solution. It requires paying money for VM software, either a more expensive version of Windows, ie Pro, or a 3rd party program (yes there is freeware, but not for business use). And you have to buy a separate Windows license to install inside of the VM. And depending on your VM tool, and how it is setup, you may not be able to share information between applications in the native windows and VM.
All in all, it would have been better if MS had designed Windows to totally isolate 32 and 64 bit application installations, allowing both types to be installed on the computer at the same time, but they didn't. Don't bother to tell me it's not possible.
