execute custom action only if setup failes

[TimoZimmermann]

In an Basic MSI project I want to execute a custom action only if the setup failes. How can I do this?

Is there a property which I can use in the condition of the custom action?
And where must the action be sequenced?

You might look into using a "rollback action".

Generally, you'd sequence a rollback custom action immediately prior to the custom action that you're cleaning up.

Rollback custom actions are a type of deferred custom action, and need to be sequenced between the InstallInitialize and InstallFinalize actions.
