Anti-Cheat Police Department, a Twitter account that aggregates reports on cheating in online games, recently collected some forum posts from users having issues running Valorant on Windows 11. They show a “VAN9001” error that seems to occur when trying to play Valorant on Windows 11 without TPM2.0 or secure boot enabled. The screencaps of the posts seem to confirm Riot is requiring both to play Valorant on Windows 11.
Windows 11 itself already requires TPM 2.0 which has caused a considerable amount of confusion among users trying out the operating system before its full release later this year. Secure boot seems to be what’s confusing people trying to play Valorant, as tutorials on how to fix VAN9001 mostly involve activating secure boot in the BIOS.
