Device Activation Failed


Recommended Posts

I received today my activation code its name match exactly

My system is windows10 64bits home version, just installed

The board is the last version Nucleo .... with last firmware and so on

With Pin2dmd.exe => Device activation failed

With 64bit version with the menu activate => Device activation failed

Connection USB seem ok I can see it 

I searched on pin2dmd.com but I don't see what I forget

Is it possible to test the connection between Pin2dmd.exe and the board before activation ?


Thank for your help
