Please try this:
kpse.set_program_name('texlua')
dofile(kpse.find_file('lua_altopt.lua'))
AFAIK require() expects a name without an extension but kpathsea needs
the full name, of course. Thus, you could also try
kpse.set_program_name('texlua')
require(string.gsub(kpse.find_file('lua_altopt.lua'),'.lua$',''))
but using dofile() looks more straightforward to me.
I assume that you got lua_altopt.lua by running tlmgr update,
otherwise you shouldn't forget to run texhash.

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
