ECHO Installing AIM 5.2 ECHO Please wait... start /wait %systemdrive%\install\Applications\AIM\Install_AIM.exe /s For MSN Messenger it would be this... ECHO. ECHO Installing MSN Messenger 6.0.0602 Final ECHO Please wait... start /wait %systemdrive%\install\MSN\MsnMsgs.msi /QB (http://unattended.msfn.org/xp/applications/msnmessenger.htm) What about Yahoo Messenger?
