The x86_64-pc-windows-msvc and x86_64-pc-windows-gnu rustc targets require Windows 10. You would have to compile for x86_64-win7-windows-msvc instead, but I don't know if Wasmtime itself doesn't also use any API that Windows 7 doesn't support. https://blog.rust-lang.org/2024/02/26/Windows-7/

I'll echo @bjorn3 in saying that while not intentional per-se it's also not guaranteed that Wasmtime runs on Windows 7. This is a platform which will require being explicitly ported to if it doesn't work by default. We are happy to evaluate and review such contributions of course.
