It would be helpful to add to LuaRT distribution a pre-built luac.exe bytecode compiler version compatible with the LuaRT environment.
p.s. I tried to use a luac.exe I compiled by myself using MINGW 64-bit but I got this error from dofile():
"bad binary format (lua_Integer size mismatch)"
UPDATE: using a pre-built binary luac54.exe downloaded from [Login to see the link] (lua-5.4.2_Win64_bin.zip ) I solved the issue, but still it would need to find the right exe every time LuaRT is updated
