Well the mboard you have now worked before, you could always try the method below… (or borrow anyone’s W10 Pro DVD and install to a clean drive)

@CaptainCoop779

Or if you have a spare hard drive, put it in your PC, load Windows 7 (assuming you have that disk), then do the upgrade to W10… maybe that can be a test then do all the Sim installs fresh, get it working then clone over to your existing drive or a faster bigger drive if you want.
