A good rule of thumb on Windows when you run a command through C
(which Lua uses) and the command contains double quotes, is to
surround the whole command with an additional pair of double quotes.
So your script should become:

path = [[""C:\program files\lua\lua.exe" "C:\Users\name surname\test.lua""]]

You can type "cmd /?" in a console for an explanation of what's going
on in details.
