I tried both of the above solutions, I disable the auto mount and closed 
all folders, I also create a local directory and started the 
installation from the command line but the problem still exists.

I tried to force unmounting the drive then ejecting it by using:
umount -l  /media/cdrom
eject

and I successfully ejected the cdrom but matlab did not recognize it as 
CD2 and still considering it as CD1.

so I tried to force mounting it using mount /dev/res0 /media/cdrom, but 
I got error saying /dev/res0 is busy or already mounted.

Thanks Guys
