I'm just putting this here in case someone else runs into the same problem I did.

HH optimizer not launching; click it and nothing happens, nothing in task manager, no error report generated.

Uninstall and reinstall several times, no change.

Apparantly the issue has to do with MS one drive cloud thingy. I don't understand the tech aspect of things.

But if you do a fresh install into a new folder on your HD instead of the default pathway it should work the way it's supposed to.

A couple of my cluster mates had the same issue I did, and the fix worked for them as well, so I figured I'd post the solution for everyone.
