Detect smartassembly

[beBoss]

Well, how to detect which version smartassembly is used ?
I want to crack one program called vloader, but it's "packed" with smartassembly and I can't see the code

I'm really noob in .net reversing and I need your help.
Here is it the program:

or download it from official site:

http://vloader.bg/

p.s. Click ot the green button to downlaod the program setup.
p.s.2 I don't do the request ! I will try myself to revers it but i need help to know which version is it and eventually how to decrypt/unpack the vloader.exe

thank you !
