Ubuntu – Installing matlab on Ubuntu 12.04 32bits

I am trying to install Matlab on Ubuntu 12.04, I have a 32bits machine. I downloaded the files and set the file install to exectable, then run :

$ ./install -v

but then I got the error :

Error : Cannot locate Java Runtime Environment (JRE).
The directory /Unix_MAC/sys/java/jre/glnx86/jre does not exist.

So I decided to add the path of matlab's jre to the command ( But before I went to sys/java/jre/glnxa64/jre/glnxa64 and changed the file java to executable), then tried :

$ ./install -v -javadir /home/mbenseddik/Unix_MAC/sys/java/jre/glnxa64/jre/

But then I got the following error :

Preparing installation files ...

    Command to run:

It seems like it is looking for glnx86 whereas the only directory inside the sys/java/jre directory is glnx64…

Any idea on the matter ?
