i can just run it though manually i have done it before anyone that can get me a link if there is manual version that'd be great otherwise devs will need to fix this otherwise i won't care to play the game if my anti virus program thinks its a virus
Install as you did previous non-launcher versions.
However, you should really look into a new AV program. Norton is incredibly bloated and has been known to be fairly inaccurate with its detection in recent years with a lot of false positives and detection failures. There is a reason it has a pretty bad reputation in the PC community (Almost to Internet Explorer levels)
//edit:
Also, Norton decided to go with some community bs, so if program is unknown is marked as suspicious. Don't use program if you don't know how it works.
