So I've been wanting to try viveport infinity, but it seems the universe is telling me off for even trying. When I install it seems like everything is going alright but after I sign in I get a window popping up saying there is a unexpected error and it shuts down. Out of curiosity I checked the Vive folder and it's nowhere near the 18.5 Gigs it says it will need. So I am utterly confused, does anyone know what's going on?
