Ok Mazin, yes and no, runonceEx from cd works. Yes if I deselect Library and no if Library is allowed to install. So to explain, no matter what I do if I choose to install Library then to get winamp to terminate I must use taskkill. If I deselect Library, then runonceEx from CD works fine just as you have it here. My guess is that extra window that opens, something about nothing in library yet, I can't remember what it said, is causing the problem, just a guess? Very clean no cmd windows,very nice. bonedaddy
