Malwarebytes Anti-Exploit

This is not the newest version, but is the version prior to it. The newest version of this when installed prompts Windows to pop up a banner across the screen informing that "This program will not run on your system. Please contact the maker for another version..."

So, you ask, "What's it do, anyway?" It provides zero-day protection against malicious exploits by malware that is not yet on database lists. And you'd like to know "Why doesn't the newest version work for you if this one does?"

Please Note: 

Malwarebytes Anti-Malware itself was recently given a major upgrade, and is itself a zero-day protection program. Here's what they say about it:-

 

Back in the heyday of Windows XP, there was a program called 'ThreatFire' which did essentially this same thing. It was a very good program, and probably still is....

...but its latest update is version 4.7, which came out on November 25, 2009.
So you can try it if you like, but I'd recommend this newer Malwarebytes one instead. Because today is the tomorrow we worried about yesterday.
