I'm beginning to think that there's an incompatibility with this hardware and the most recent RogueKiller.
A very similar issue exists with the latest Malwarebytes.
See:

On this system:
Google Chrome (the latest) will not install and the installer says it's incompatible with the hardware.
Firefox will install. Bitdefender will install. They both work fine.
Malwarebytes, in an older version will install and run but not the latest version.
