Hi again,
OK I get the problem. Please launch the expert .EXE directly from here: C:\Program Files\SAP Predictive Analytics\Desktop 2.1\Expert\Desktop, the EXE is called SAPPredictiveAnalysis.exe. You then get a pop-up message & get the possibility to use your second license key.
The fact that expert analytics part is grayed is not expected - we have another open thread on this - I will forward.
Thanks & regards
Antoine
