I have a major upgrade patch and at the end of the patch install, RemoveExistingProducts action is invoked and it removes the previously installed version of the product. But while doing that, it executes a CA with condition set to "Installed" that helps to remove some of the registry entries. I want to prevent executing this CA when RemoveExistingProducts is in action. How to do that? Please any help would be really appreciated. Its very urgent.

Thanks.

Registry entries are best removed using the Registry table.

You can use the component conditions $ and ? to determine what is happening to a related component then use that to determine if a CA should run or not.

You are changing the system.  Your action should be deferred before InstallFinalize and contain roll back code.

Hello, Ian.
I have similar problem with CA, which executes during RemoveExistingProducts.
This CA has condition “NOT Installed”
How can I prevent this CA from execution during major update?
What is the new condition?
May be there is some special property, or missing some property ?

Thank you in advance,

Regards,

I want to correct my mistake.
Condition to Custom Action was "Installed"
But problem stayed.

Try

$RelatedComponent=2

$ Action state for component.

The action will run when RelatedComponent is being removed.

In the major upgrade this should only be the case if RelatedComponent has been made obsolete.
