hi
in two seperate cases when i used LaunchApp or LaunchAppAndWait, the exe which i run hangs, it's process is available on the task monitor but nothing happens.
when i run the exe manually or from start-->run or cmd, it works perfectly.
i tried changing the working directory before launching, i tried using LaunchAppAndWaitInitStartupInfo ( ), but nothing seems to help.
i worked around this by running a batch file which runs the exe, but this is not a perfect solution (i monitor the returned message for logging purposes).
any ideas will be appriciated.
thnx

Maybe the launched exe uses SendMessage to broadcast a message to all running applications? If it's waiting for a reply this would lead to a deadlock (as far as I know InstallShield doesn't respond to such messages while waiting for the launched application)

hi stefan
the exes i launch are DirectX 9.0b setup and VoiceTest of windows. as far as i know they are not waiting for any reply.
further more: i launch them both successfuly in some other scripts, but i sometimes can't make them work.
thanx for ur reply

Don't know if this will help, but it could be a problem with the IS engine trying to be reinitated. You could try to use DoInstall instead of LaunchAppAndWait.

Good luck
