Programmatically extract contents of InstallShield setup.exe

There’s no supported way to do this, but won’t you have to examine the files related to each installer to figure out how to actually install them after extracting them? Assuming you can spend the time to figure out which command-line applies, here are some candidate parameters that normally allow you to extract an installation.

MSI Based (may not result in a usable image for an InstallScript MSI installation):

  • setup.exe /a /s /v"/qn TARGETDIR=\"choose-a-location\""

    or, to also extract prerequisites (for versions where it works),

  • setup.exe /a"choose-another-location" /s /v"/qn TARGETDIR=\"choose-a-location\""

InstallScript based:

  • setup.exe /s /extract_all

Suite based (may not be obvious how to install the resulting files):

  • setup.exe /silent /stage_only ISRootStagePath="choose-a-location"
