TestComplete silent install return ResultCode=-3 with InstallShield

Hi,



I'm not sure if i'm doing something wrong, but i created a response file from my TestComplete manual installation following these instructions :http://support.smartbear.com/viewarticle/56424/



but now, I have tried to install it in silent mode with these two command lines and it cause the same InstallShield ResultCode=-3,



setup.exe" /s /f1C:\pathtoissfile\setup.iss /f2C:\Temp\log.txt

or simply

setup.exe /s



the response file is in the same folder as the setup.



According to this site : http://helpnet.installshield.com/installshield18helplib/IHelpSetup_EXEErrors.htm



that means The installation exited because the end user canceled the installation, but i never selected any option.



Is there anyone who know what could be done to fix the issue?



Thanks
