DanMardan so weird story: Originally my rtc compiled lua without some ui module "yes i did the -w" Then i wanted to reinstall luaRT as a whole thinking my version was bugged and now i get this: error loading module 'ui' from file 'C:\Users\486B1\AppData\Local\Temp\___modules\ui\ui-static.dll': %1 �� �������� ���������� Win32.
Samir You may have melted x86/x64 installations or melted LuaRT versions, uninstall all of LuaRT and reinstall latest release Try to files of your Temp folder it may help too
