I bought Vive Cosmos.
Read instructions, tried to install ViveSetup. I tried install it without headset plugged and with headsed. Nothing happens. Alaways got this: https://prnt.sc/prlseq
Than tried to google that problem. People said that I can just use SteamVR and it will be ok. I tried to install SteamVR and connect VR Headset. Nothing helped me, stemvr can't see my headset.
What should I do to use it?
