Fixed, but with some things to do !
I don't understand why BIS didn't it itself, it would be better for everybody who want to try those tools.
Thus, for those who want to launch Arma 3 tools without installing nothing else, follow this :
1- define your own directory as "P:" , like this : http://tom4897.info/blog/2014/06/arma-3-tools-p-drive-devp/
2- set your setting.ini like this for example : http://forums.bistudio.com/showthread.php?175729-Prepare-P-Drive-not-working-cannot-find-registry-key-or-value-error&p=2815981&viewfull=1#post2815981
