Hi, i've been having a spot of bother with my silent installs. i'm using the guirunonce method (relevant files attached) what seems to happen is it does the .net stuff and the windows media bits then rapidly fires through the rest and restarts. or possibly it restarts then rapidly fires through the rest, I'm not sure, sorry. once restarted, only the .net stuff and wmp is installed the application event log shows no attempts to install the others. also, it only tries to install on the second login, not the first. i.e. windows finishes installing and boots into windows, then i click loggoff and when i log back in, it THEN runs the install apps. not sure why. hope you can help...
