installshield

I have a setup.exe file generated using installshield suite project (.issuite) file. For an admin or a general user with sufficient privileges, one of our IT admin is able to do a silent installation using - setup.exe /silent However, when tried to push the installs using SCCM (System Center Configuration Manager) or using PSEXEC (both use System account to install), the install fails.

I am trying to extract the file-contents of an InstallShield setup.exe-file. (My plan is to use it in a back-office tool, so this must be done programmatically without any user interactions.) Is this possible? (Initial research seems to indicate it will fail.) If it is possible to have a generic solution, for all recent versions of InstallShield that would be best. Otherwise, if a solution only works for some versions of InstallShield it would be a step on the way. (It would probably be possible to deduce which InstallShield version a setup.exe is by looking at version resources of the exe
