Wix: Which CustomAction is called just before showing the failure screen?

Question

I have a requirement wherein I need to execute a custom action if the installer fails (either automatically or manually failed by returning ActionResult.Failure from another custom action). I tried <Custom Action="CallMe" After="InstallFinalize"></Custom> but the CA is not called. Any help is appreciated.

Edit: Found out from logs that it is "FatalError" custom action. But then doing this <Custom Action="CallMe" Before="FatalError"></Custom> throws Error 8 Unresolved reference to symbol 'WixAction:InstallExecuteSequence/FatalError' in section 'Product:*'

Answer 1

You can use

   <Custom Action="CallMeCancel" OnExit="cancel" /> 
   <Custom Action="CallMeError" OnExit="error" />

The values for OnExit are success, cancel, error, suspend
