PC Beta Install

i was invited to the beta but no longer use a console how do i install on pc

You should have registered to the PC Insider program instead of Xbox. There were am option and you should had selected PC instead of Xbox, now there is nothing that can be done, if you got an invite for the Xbox flight you can’t use it on PC.

This is not the right board for that question though, there is a Halo Infinite forum, you asked on Halo 5 one.

This is not a Halo 5 issue
