Nod32 has just been instaled on all out computers here. some are running Windows XP, some ME, and some 98. For the non-xp machines, the execute external application dows not work. I have tried running NOD32 for a clean-scan, and nothing happens, either when scheduled, or run via the "Run now" Right click menu. I have also tried notepad as a check, and it doesn't run either, Is task-scheduler required to schedule execution of an external applications. If so, is it still required to a "run now"?
