[ANSWERED] MPT devices driver failing

Hi.

Maybe someone can be a quick help. Have build a Windows 7 custom one where my phone got installed fine. Tried to connect in vmware full installs and that went fine also. My new Windows 8.1 install has trouble with installing the mpt driver. It gives the error after installing.

'The install class is not present or invalid.'

Using:
Windows 8.1 Pro N

Have I missed something? Maybe someone could point me in the right direction.

Maybe it's my preset or the Windows 'N' version. Going to review my preset with a standard 'core' version and build a new one.

Thanks.

That's the N's problem. I've got that error before and I had to switch to Pro version
