Valorant uses its own Riot Games based launcher

1. Download and install the Game Client Link

2. Create or Log in with your Riot Games Account

3. Reboot - this is required as the Riot Anti-Cheat engine requires essentially a kernel level driver to be loaded at boot.

Special note: if you have an old riot games account (used for League of legends and other games) there is a chance that your account has been shadow banned over the years of data breaches with the company. I am not aware of a way at this time to check the status of your account, but the easiest way we reproduce the issue is if you CANNOT see the game someone is hosting and your account is years old, changes are it was compromised and shadow banned. in 2020, we had 2/8 people have this happen.
