    I have a custom desktop with an Intel DG31PR motherboard. I have previously upgraded two identical units to Windows 10 9103. The unit in question is running Windows 7 and "coreinfo" indicates it passes all required tests including CompareExchange128 or CMPXCHG16B. Still I get the message that the CPU lacks an important instruction called as CMPXCHG16B. The processor is an Intel Q9400. How can I get past this error by the installer?

    :)

    I am told that Windows 10 64 bit would not have the CompareExchange128 hardware support requirements that came in with Windows 8.1, but I am receiving the error telling me it is not compatible because of that. I have read the requirements my CPU meets them
    all. It is an old AMD 64 X2 3800+.

    Why is this happening?
