Facebook sdk Keytool not found (again >_<)

Hi there, so here's my problem, i'm trying to add facebook support for an android game, but the keytool doesn't seem to be found, i looked on the net and did the following things:

- install open ssl, then pul the following path in the environment variable "path":
;D:\INSTALLS\OpenSSL\bin

Then i downloaded the java sdk (jdk1.8.0_65) and did the same thing:
;D:\INSTALLS\Java\jdk1.8.0_65\bin

Then i created an environment variable "JAVA_HOME" with the following value:
D:\INSTALLS\Java\jdk1.8.0_65

I restarted unity and still have the same message being prompted:
https://gyazo.com/91e93267979876671e810827580b083d

I'm a bit lost, i managed to create the key hash using directly the keytool command but i've got an error saying that facebook settings aren't correct. (because it doesn't find the keytool)

Anybody has an idea how i could fix this ? i'm using unity 5.1.2f1 and the facebook sdk 7.2.1

Thanks for reading

 

EDIT: ok so i managed to get it working, since i knew that the command was working, because i just used it in windows cmd prompt, i just commented the following lines in the "FacebookAndroidUtil.cs" file:

Code (CSharp):

1. if (!DoesCommandExist("keytool"))
2. {
3.        setupError = ErrorNoKeytool;
4.        return null;
5. }

It seems to work just fine now
