    I simply fixed my issue by disabling AV and then running the setup as administrator.  Hope that helps.

    Hi John,

    Did you try to run the setup as administrator as Vin suggested in the above comment?

  • John Nowlin

    Actually i found the problem, our IT department was testing a program on the network, where they must white list programs installed. . .the installer was fine, but needed to be added to the white list of acceptable programs.

    All resolved.
