only when using paths from Lua. This case is invoking the os command processor, which expects the native directory separator, which happens to be a backslash on Windows.
Thijs
It's best to use forward slashes in your file paths!

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""]]
print(path)
os.execute(path)
You can type "cmd /?" in a console for an explanation of what's going
on in details.
