If you're trying to install the MSIX build of Affinity V2 on Windows and it's failing with the following reason:
Windows cannot install package ... because the package requires architecture x64, but this computer has architecture x86. (0x80073d10)
This indicates that your machine doesn't have a 64 bit CPU. Our apps require a 64 bit CPU to install and run.
