DCX2496 software

I downloaded DCX2496 remote editor software V1.16a to check it out before buying the unit. The software seems functional but its window is only partially visible with no way to expand it or get to scrolling controls. Does anyone know if it only works if the pc can first comunicate to the unit? DL it twice and tried on multiple puters.

looks like this:
