I have a few issues with the beta launcher, first of which is that steam does not even show the options for using it what so ever, steam says it doesn't even exist. there is not even any option which allows me to choose from other than opt out of betas.
the second is when I manually download it from the main website, it appears as thought it installs separately from steams install even if I do in fact install it into the same directory or place as steam. it will run as its completely own install all files from steam do not migrate to it, or vice versa. so what is going on or why that happens is above my understanding of programming.
and I'm using windows 10, and the version I tried to use was the one available in the main sites links so I cant say how that affects things.
