Horizon not downloading

Hey, I have downloaded this recently around last year, but it was deleted. It has been around half a year now and I am trying to download it onto this dell computer. When I click “run” it starts and then stops and says “this program could not be downloaded.” Then it gives me a retry button and that wont even work. What are the reasons this may not work? I have a feeling it is the adware antivirus program we have downloaded on here but im not positive. Thank you and please get back to me soon.
