Hi,

Which is your MPLAB version ???

and

Did you add the Paths to PBP and MPLAB in the Windows environment ???

Alain

What version of MPLAB are you using? The newer versions of MPLAB will not work with the old versions of PBP.

Did you follow the instructions on MeLabs web site?

And I have to ask...
If you are new to this where did you get such an old version of PBP? It is not sold anymore.
