Hi all, my first post... maybe it's a noob request, but ive search in many topics without findin how ive to do... I go a problem with "quicktime 7" in command lines of start.cmd With this command line --> start /wait %systemdrive%\install\qtime\qtime7.exe /S/v/qn quicktime's insttallation starts, complete silent, but not wait and go immediately to the second program to install. I've tryed usin sleep command, but still not works: maybe I dont use "sleep" correctly? I've used this --> start %systemdrive%\install\qtime\qtime7.exe /S/v/qn sleep 150 and start sleep 150 %systemdrive%\install\qtime\qtime7.exe /S/v/qn But no way... Can anyone explain me how to use sleep? Thanks for all the reply, and sorry if there is a similar topic i havent found
