    Hi, I am trying to download the academic version Cplex Optimization Studio (CJ8GXML) onto a Linux machine. As I only have access to the Linux machine via SSH (only console), I would like to download the setup bin file while only accessing the command line. So far, I have copied the download URL of that Linux bin file from a local (Windows) machine (from Download via HTTP option on https://www-03.ibm.com/isc/esd/dswdown/searchPartNumber.wss?partNumber=CJ8GXML) and used wget to download the Linux bin file successfully in the remote Linux machine. However, after installation, the version installed is a free community version. Is there a better way to do this? If not, is there a way to download the installation bin file without using a browser?

    Thanks,

    Hello,

    I don't think that your using wget to download the installer can have an impact on what version you come up with.  Either you downloaded the correct version, or not.  What is the name of the file that you downloaded?
    The default install directory name for CPLEX Optimization Studio has 'Community' in it when the installer is for the Community Edition.  If you didn't change the default install directory, this may be a way to confirm what you have.
    Finally, if you use Python, you may have unknowingly installed a Community Edition version using e.g. pip.  Please run
    python3 [COS_install_dir]/python/setup.py install​
    while making sure that `python3` in the command above is the same environment that you use later to run your CPLEX Python programs.

    There was indeed the lingering of an old version. Thanks!
