uninstall silently in background using setup.exe

I want to uninstall a software which is installed using EXE not MIS. By running the uninstall Strin in CMD i can able to uninstall but its asking conformation messages.

My intention is to uninstall it silently

 "C:\Program Files (x86)\InstallShield Installation Information\{2EA86967-B3D3-4B2E-9DE9-28A595AF2E2E}\setup.exe" -runfromtemp -l0x0409  -removeonly

I tried this command but its asking so many conformation messages for uninstall. Is there any attribute I can add here so that it will uninstall in background
