I am creating an installer that installs several programs and file packages at once, one of these being WinZip, I want the WinZip installer to run in the background, from what I've gathered using `/s` will make it run in silent mode, BUT the installer still doesn't install. I believe that is because of the selections one must make during the WinZip installation process. so my question is how could I set this up to silently install WinZip in the background? would I need an Answer file? if so how do I get that set-up? any help would be great!

\*snippet of my code in the NSIS file:

```
Section
IfFileExists "C:\Program Files\WinZip\WINZIP32.EXE" Dont_Install 
SetOutPath $TEMP
File "Installerfiles\WinZip165.exe"
DetailPrint "Starting Winzip installation"
ExecWait "/s WinZip165.exe"
Delete $TEMP\WinZip165.exe
SetOutPath $INSTDIR
Goto done
Dont_Install:
MessageBox MB_OK "You seem to have this program \
(WinZip) already installed"  
done:
SectionEnd

```

\*note I have seen the other questions on having a silent install, this question is more WinZip specific and pertaining to how I would establish an answer file if need be.
