Value of $VIM differs 7.4 2344 vs 8

Hi,

With this folders structure under windows 10 :
- Vim/
|+ awesomeplugins/
|+ third_part/
|+ vim74/
|+ vim8/
|+ vimfiles/
| _vimrc


The "echo $VIM" command returns :
pathtovimstructure\Vim when executed from gvim.exe version Vim7.4 1-2344
pathtovimstructure\Vim\vim8 when executed from gvim.exe version Vim8

Both version compiled with same Makefile, I don't understand. Can you help me cause it crash my existing structure of vimfiles and third part of mine.
Thank you
Niva
