Can't find the patch 1.7.2 for Space Rangers 1

[Vertex]

Hi,

I've just bought Space Rangers 1 a few month ago.
Today i noticed that the version of the game is 1.7.1. But on wikipedia (http://en.wikipedia.org/wiki/Space_Rangers_(video_game)) i see that the latest patch for the first Space Rangers is 1.7.2. But i can't find it!

Someone know where can i find it?

Thanks in advance for your support (and sorry for my bad english )
