In the command-line parameters for the package, specify the response file name. For example, if you are packaging a TEST-Install.iss, setup.log, and TEST.exe setup program together, you can specify the file names in the command-line options as follows (assuming that the mapped drive is the Z: drive):
c:\test_temp> TEST.exe /s /f1"Z:\test_temp\response\TEST-Install.iss" /f2"Z:\test_temp\setup.log"
