FTDI drivers installation

After software installation, the FTDI CDM Drivers need to be installed, if not already installed. When the user

runs the "Current Sensor Evalkit Vx.x.x.exe" file a parallel window to the installer window is automatically

opened at the end of the installation procedure. Click on the "Extract" button to continue the driver installation

procedure.
