I don't know this version, but it's an "old" one.
I personnaly still use the 3.3.2, and the 3.x can be found here (see further down for others):
https://github.com/GuntharDeNiro/BTCT/releases/tag/v3.3.5Otherwise there is 4.x version, and 5.x still in development, no GUI apart a node.js server one, in short, to watch on your browser.
There are also 3rd party GUI's available, some very interesting (to be paid, I'm afraid).
But If you're beginning, I'd recommand to start slowly with a 3.x version until you understand strategies, parameters, limitations, etc.
