Prosim 737 or Prosim 2.24 and above

Can anyone here tell me what the differences between the two.
I currently have Prosim 737 and trying to download Navigraph. I’m not sure whether to download Prosim or Prosim 737 2.24 and above. can anyone explain the difference thanks. I’m currently operating Prosim version 3

Then you should use “ProSim737 2.24 and above”
