Requiring Lua dll on Windows 11 throws "not a valid Win32 application", luarocks install fails

[Clemapfel]

Attempting to download the lua version of this library using luarocks on Windows 11 throws:

> luarocks install --server=https://tinyspline.github.io/lua tinyspline
Error: No results matching query were found.

Manually downloading the luarocks package and installing it or requiring the approriate dll directly throws

> require "tinyspline"
error loading module 'tinysplinelua51' from file '.\tinysplinelua51.dll':
        %1 is not a valid Win32 application

I am on a 64-bit Windows 11 system, tested with luajit and lua 5.1

I tried the above commands on linux and everything works perfectly there, including directly requiring the shared library, this only happens on windows.

Is your Lua installation a 32-bit version?
