This can occur under certain Windows configurations.
One workaround, is to first run the PowerCore software installer program, and then use the Windows Device Manager to do a manual installation of the drivers from there:
Rightclick on PowerCore and select 'Properties'. Then click 'Update Driver'.
When you are asked to provide the path for the PowerCore drivers, please point to the folder where you have extracted the file below.
