Uninstall is still running after installer exits

I am not sure how to put this here, I will do my best. Please help me out

I have a patch installer, which installs and uninstalls as expected. But after uninstalling the patch from program files, I have tried uninstall other software. All I got a pop message saying that let the uninstall finish uninstalling.

All I figured out is at the end of uninstalling my patch, I am starting a process by executing .exe file. My uninstaller waits for that process to quit, which I do not want to quit.

Other option I have is to force the user to reboot after uninstalling the patch, which I do not wish to do.

I tried Exec, ExecDos, and ExecCmd with /ASYNC, but I still see the same problem.

Try 1

ExecShell open "$INSTDIR\system\teven.exe"

Try 2

ExecDos::exec /NOUNLOAD /ASYNC "$INSTDIR\system\teven.exe" ""
Pop $0
ExecDos::isdone /NOUNLOAD $0

Can anyone help me to solve this. How can I start teven.exe and left it running and make my uninstaller not waiting teven.exe to quit.

You pretty much have to force the uninstaller to wait if you are going to do other things after the uninstaller completes. When you uninstall from Add/Remove programs Windows even forces a wait for all your child processes started by the uninstaller...

Why are you using /ASYNC if you want to wait? (Edit: I guess you don't want to wait?) ExecDos::isdone does not wait, it just checks, use ExecDos::wait if you want to wait.

If you are not using advanced options and don't need stdin input then you don't really need to use 3rd-party plugins:

If teven is a console application and you want to hide the console window (and wait):

nsExec::Exec '"$INSTDIR\system\teven.exe"'

otherwise:

ExecWait '"$INSTDIR\system\teven.exe"'

If you actually don't want to wait you can just use Exec but Windows might force a wait anyway when uninstalling...
