It is common that install programs is 32-bit even if they install a 64-bit driver and on "normal" Intel Windows you are suposed to call \windows\sysnative\rundll32.exe when installing a 64-bit driver from a 32-bit script. (because if you just call rundll32.exe without path you would install the 32-bit version of the driver)
My question is if this logic still applies to ARM64?
