Hi,

I've created a deferred custom action which is called after installFiles step of the msi.
My problem is that irrespective of whichever error code I return from this custom action MSI ends with error 1603 (Install Failure), and show same error at the finish screen.

Is there any way via which the error returned from my custom action can be trapped and corresponding error prompt or error string can be shown?

What is the value in the Return Proccesing field of the custom action?

I am returning 27555, as I read some where that msi reserves range 20,000 to 30,000 for custom action return codes

Just to clarify further, I've a custom action Dll whose exposed function is being called via msi. If I look into msi logs error code gets printed as an output from custom action.

All I want is that on the basis of error code returned by custom action some specific alert should be thrown. My custom action is a deferred one.

one line above the line where you see that the custom action is defered there is an option called "Return Processing" (attached). when calling a dll there should be 3 options, which one you use?

I've set "Return processing" set as "Synchronous (check exit code) "

Maybe you should try to change it to synchronous (Ignores exit code)

I don't believe you can "capture" the return code from a dll and condition further action based on it. If I understand it correctly, a return code of anything other than zero will cause the MSI to fail and rollback if you use "Synchronous (check exit code) ".

(And since it is a deferred action, you won't be able to set a property to use in conditions after the custom action.)

What you may want to try is to have your dll itself display the alert, then return 0 if you want the msi to continue processing, and an error code if you want it to stop and roll back (or just set it to ignore the exit code and it will always continue).

Or save the exit code to the registry or file.
