Hi all,

I want to do a major upgrade to my product. When the uninstallation of my older product through the removeRelatedProduct action, Is it possible to set a property for the old product installation. I need to do that sothat I trigger a custom action that is conditioned on that property.THis is so important......

Thank you all

When a setup is being silently uninstalled as part of a major upgrade there is a special windows installer property called UPGRADINGPRODUCTCODE that is set. You can use this property to condition a custom action to run only during major upgrades.

Hi,

Thank you. That is so good. But what if the old installation is already released. Is there is any way to set another property in the old installaion through RemoveRelatedProduct action.

Thank you

The UPGRADINGPRODUCTCODE property is a built-in windows installer property. It is set whenever the FindRelatedProducts and RemoveExistingProducts actions find something to remove. What property are you trying to set, and what are you trying to do?

No, I don't think you can set any custom property for the uninstall of the old version during a Major Upgrade.
You could instead uninstall using a custom action calling msiexec.exe, but that would only work during the UI sequence, i.e. not in a silent upgrade scenario.
