Problem calling an InstallShield setup
Hello together!

I tried to call an InstallShield-Setup from my NSIS Setup with Exec (not ExecWait), because I will try to figure out, if the InstallShield Setup hangs without responding (this happens in some cases). E.g. the script loops while there is a process named '_ISDel.exe'. If the process '_ISDel.exe' is still active after a certain time, i will kill this process and show a message, that the setup fails.

The Problem is, that the InstallShield-Setup hangs, when called with 'Exec'. It will proceed, if I kill the NSIS Setup-Process.
The InstallShield Setup will work as aspected when called with 'ExecWait' - but than I can't detect, if it ends after a certain time.

Do you have any idea ? Is the InstallShield-Setup detecting, that an active NSIS-Setup is running ?

Hope you can help.
