Not sure i understand , did you mean the full x86 architecture or just 32 bit as opposed to 64bit  ?  would be weird to do this at a subversion level .  I can confirm my laptop processor and OS fully supports 64bit . And 64bit is the only install option for version 8 .

I am aware that 32bit was dropped at version 8 (https://blogs.vmware.com/euc/2021/03/an-update-on-vmware-horizon-32-bit-support.html) , but im already successfully on version 8 (8.3.0) running 64bit so that cant be the issue .  

Do you have a link referring to processor drops at 8.5 , as i cant find any references.

As an aside im also sucesssfully running 8.5.1 on a 2013 Macbook Air , that has intel x86 architecture under the covers
