Perhaps I should have realised that the Embarcadero Resource Compiler action is not a “Delphi Action”, but it does contain the same Delphi compiler selection list, and I was surprised to find that these were not changed by the Wizard. Of course I did not discover this until I eventually uninstalled the previous Delphi version and the build failed. If this is by design, it would be nice to have a brief note warning about this in the Wizard dialog; otherwise, I would suggest that this action should be dealt with as well as the compiler action.
This was as designed, the wizard was only ever designed to update the delphi action. I have now added the resource compiler action to the wizard for the next update.
