Chained .msi packages are installed after the parent install. Is there a way to run chained packages installation before parent installation (or in the custom place in the sequence) ?
No, there's not. A setup.exe bootstrap can run installations before your main installer, and we support a non-chained version of this with either Setup or Feature Prerequisites. A custom bootstrap could do similarly with MSI chaining, but neither approach can do so at arbitrary places in the sequences.
You can create the .msi packages with InstallShield, but in order to run the transaction from the bootstrap, you would need to create the launcher yourself. Our chaining solution runs from the MSI instead.
