Dear Andre,
Thanks for your response. I have further questions.
Our MSDN is 'Visual Studio Premium with MSDN'.
1) with our MSDN, can we install Dynamics AX 2012? I think there is no license key for Dynamics AX in MSDN.
2) If we can in install Dynaics AX using MSDN file, how we can change license key. Is there a menu for this work?
