CA on unstall but not during major upgrade

[heiner_violet]

I have a CA with condition REMOVE="ALL" that deletes some folders when the product is uninstalled.
Now, my product needs a major upgrade. Is there a way to prevent the execution of the CA during the uninstall process of a major upgrade. I tried condition
REMOVE="ALL" And Not IS_MAJOR_UPGRADE
but this doesn't work.

Best regards, H.

Perhaps consult the MSI documentation to see if UPGRADINGPRODUCTCODE will help?

Thank you for this hint.
As documented, the property UPGRADINGPRODUCTCODE is set if a major upgrade is performed and could be used to distinguish between the two uninstall scenarios.

You should also be able to use the "Detect Property" (by default it's ISACTIONPROP1 in IS2008 at least) that is part of the major upgrade item itself.

Exactly right---the action property (ISACTIONPROP1 and the like) is for the newer version to detect a major upgrade is going on, UPGRADINGPRODUCTCODE is for the older version to detect it.
