Start-up model - AX 2012 - Model selection in start-up command

 Of course, selecting the start-up model is trivial when you only have the model name and no publisher; just use the name in the -model switch. But if you also have a publisher I found that sometimes this doesn't work, as you may receive: "Model parameter 'ModelName' is invalid. Microsoft Dynamics AX will use the system generated layer model 'Layer Model'".

 So, the solution goes like this:

 "-model=(ModelName, ModelPublisher)"
