ARM64 Office install


I've got a Surface Pro X and just installed the Window 11 Insiders preview, I wanted to try the new AMR64 Office build (I've currently been running Office Insider Beta), I uninstalled the 32bit version but when I attempt the 64bit install it fails for wrong architecture.

Anyone had luck with this yet?

@Jamie HosleyI've had the same issue, but I did somehow manage to get ARM64 version installed. I installed Office using 64-bit installer from (explicitly choosing 64-bit, otherwise it auto downloads 32-bit version), setting insider to Beta and updating.

Thanks Rok, looks like they have fixed it now, I had tried the x64 installer originally but it kept failing, I just tried it now and it installed successfully.
