Hello, After some search I didn't find any answer to my problem. I don't know if it's a bug or I do something wrong. I'm using AuoIT to install some applications and deploy it with Novell ZCM10. After an installation of a software, the AutoIT icon wouldn't disappear from the tray icon on a Windows 7 machine. The same script is OK on a Windows XP machine. I try a reboot the computer, but the problem still persists. Thank you for your help Regards
