Okay; so on the new, clean install on the new, of the new, clean local account - it works! I moved it from D drive to C drive, and have been playing over there. I thought it might be the location, but checking again over here, it's still not firing up.
For obvious reasons I would prefer it on my main account, but I guess I can work around it.
