Steam, halo infinite, invalid platform

[aquilarubra]

Hi, I get the error of “invalid platform” when I try to launch the Halo Infinite installer.

I am on Arch. From what I understand, the steam package is 32 bit, despite it is flagged as 64 bit. So, it installs the 32 bit version of Steam. Halo Infinite seems to require 64 bit. Steam launches fine, but when I get to Halo, it says “invalid platform”.

Anybody with a similar problem? Any workarounds?
