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

    I have the same problem, and I disabled Anti-Virus  and still when I try and open Pix4D I get this error.



  • Gaël (Pix4D)

    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.
