Just reply "Yes". It's not an FSUIPC4 problem, but a long standing SimConnect bug to do with trust checking. In P3D they've had the good sense to remove all that and it never gives a problem, but even the FSX Microsoft team, back when they still existed, couldn't sort it out and blamed some complexities in Windows itself.

 

Also see the FAQ subforum. The thread "FSX fails to run after FSUIPC4 first installed" is relevant.
