Your struggle is a typical reason why this sort of activity should be implemented outside of the installer. You have a problem and nothing you can do about it but just brain-storm it. :(
You cannot debug. You cannot even adequately collect the information about the problem. MSI runtime is just not very suitable for this.
Have you tried the 'WinService_InstallUtil' approach I suggested? You can freely debug it as opposite to the 'InstalledFileAction' approach.
