SetupConfigUpgradeProductInfo Property

Gets or sets the list of product that can be upgraded. Why this list? Previous installations of MSI/InstallShield can be very difficult to identify in the registry because of their moving names based on a key changing for each version. Our setup will try to find the old keys bsaed on this list, using the only registry key property of these old systems containing a fixed value, "DisplayName". And the publisher name, if provided.
