ActiveX issues while installing Flash

Good morning, I am trying to Install/Update flash for one of my technicians computer. I have never had a problem downloading flash until now for some strange reason. When I download it goes to the appropriate steps of 'run' and asks if I want to do updates which I choose yes. It starts downloading and almost immediately a message pops up saying the ActiveX control for Flash Player could not be registered. I am using Windows 7 and went to tools and tried with activex selected and disabled and will still get the same error. I have tried multiple things and still no luck. I would just use Chrome since it is installed for that but the website we use for work does not work unless its on Explorer. Also, I went and checked my addons and it it is enabled but the publisher is 'not available'. Thanks for the help.
