btw, I don't like the current luavm who installs it self under C:\Users\USER\AppData\Local\ I don't think it is a directory for the whole application but for data
further more, I prefer to a portable lua with battery which can be put on USB-disk

if I comment out the following lines in luavm.lua

--~   if source == 'user' then
--~     execf('setx "%s" "%s" >NUL', varname, value)
--~   end

--~   if source == 'machine' then
--~     execf('setx /M "%s" "%s" >NUL', varname, value)
--~   end

Then I can run luavm.cmd use luajit-2.1 to set touse luajit-2.1
