Strange, if it actually is a version problem of Windows Installer it should really be the other way around AFAIR, e.g. a computer with Windows Installer 3.0 should be able to handle a older version MSI schema but not the other way around and W2K3 (with SP1) have Windows Installer 3.1 installed automatically so it should be on the top of the food chain. Anyway I still believe that your problem boils down to an error when the Advertisement sequence is run during aas file creation, but in this case it is not that the actual sequence that is blocked, but rather something else. 1) Could you check the event log after you try to add the application, I think that Windows Installer is logging the actual error, hopefully without having to enable verbose logging, look for MsiInstaller as the Source since it would be the Windows Installer API that throws an error. 2) Could it be that the product is already installed on the W2K3 computer, this could also cause the Advertisement sequence to fail and resulting in this type of problem.

Is it a home grown package or something public? When you add a package the *.aas file is created using the Windows Installer APIs and they rely on the information in the Advertising sequence. Is this the only package that behaves like this?

You might want to enable verbose software deployment logging (see my gpolog.adm for this) and see what messages are being thrown there.

The DC is a 2K3 server. I am able to do this when logged onto a Win2K DC without error. Add Operation Failed. Unable to extract deployment information from the package. Run validation on the package to ensure that the package is correct. Would this be a result of different versions of Windows Installer? Thanks Joe
