Describe the bug

Installer fails with message "This program can only be installed on versions of Windows designed for the following processor architectures: x64"

Configuration

Expected Behavior

Logs

Anything else?

Windows on arm64 will emulate x64 if x64 binaries are used. The zipfile (portable) version of wezterm works fine (as far as I can tell), but the installer will refuse to run. That means users can't use winget to install or update and have to manually do both.

A native arm64 build would work but that might be more effort than getting Inno Setup to run where x64 emulation is supported.

I haven't tested on native windows arm64 installations (like a Surface Pro X), but I have access to one if that helps testing.

I'll accept a PR that allows the inno setup stuff to run on arm64 and allow emulation to kick in, but I have no way to validate it

I have a patch that works for x64 emulation on arm64. I will make sure this doesn't break native x64 and that it properly works or reports errors on older versions of windows and will send a PR your way.
