Checking return codes

[Justin]

I am trying to install a Microsoft update package along with my regular
InstallShield installer. I use a custom action that launches the executable
and wait for it to return before continuing. The update executable can
return non-zero success codes to the installer (ie. reboot needed). The
problem is that if any non-zero code is returned from the custom action,
InstallShield throws up an error to the user and the installation fails. Is
there a way that I can get the installer to accept certain non-zero return
codes?

[Carolyn Napier [MSFT]]

A custom action marked as msidbCustomActionTypeContinue will ignore all return
codes. Outside of that, only ERROR_SUCCESS is treated by Windows Installer as a
successful return code. For more information consult the Windows Installer MSDN
help topic "Custom Action Return Values".

Note that you could also use a DLL custom action that invokes the executable and
then depending upon the success or failure returns an appropriate error code. It
could also schedule a reboot if necessary.

Hope this helps,
