    Hi,

    Can you please let me know the latest released version under CPLEX12. Currently we are having CPLEX12.1 and I believe CPLEX12.2 is already released. Can any of you confirm.

    Also, could you please provide where I can get the system requirements for latest version of CPLEX.

    regards

    The above webpage points to a System Requirements link which takes you to a page where you can click for information on the various operating systems (AIX, Windows, Linux, etc.).

    Faculty and researchers at accredited institutions may be interested in the IBM Academic Initiative, under which ILOG software can be downloaded at no cost.

    Hi, I just have reinstalled my Windows, and installed the newest version of cplex 12.2 (academic version). I have followed the steps to install access.ilm file but i have not succeeded. It shows the limit of 500 variables and 500 constraints (i already restart my computer after the installation).

    Typically, I run some small inputs to debug my code in my computer and let the server run the big input (which already installed cplex 12.2). But now, I can not run small input which I could run before.

    That means there is some problems with my access.ilm file? or my lab is downgraded?

    Thanks,

    Lessi.

    I downloaded the ilm file at home so may be it is a problem. Before I downloaded this file at the laboratory.

    I can run cplex but there is a message about the number of variables & constraints (500). I had no problem with the previous version of cplex (12.1). It seems that cplex has not recogized access.ilm in the c:\ilog\ilm folder.

    It seems like you are using an old license file that limits the problem size to 500 variables/constraint.
    Are you sure that your ILOG_LICENSE_FILE environment variable points to the license file you downloaded for the AI edition? Or may it point to an old license file?
    Can you print out the value of this variable right before you instantiate CPLEX? I.e., do something like this
    /* In C */
    printf("ILOG_LICENSE_FILE='%s'\n", getenv("ILOG_LICENSE_FILE"));
    status = CPXopenCPLEX(...);
    ...
     
    // In C++
    std::cout << "ILOG_LICENSE_FILE='" << getenv("ILOG_LICENSE_FILE") << "'" << std::endl;
    IloCplex cplex = new IloCplex();
    ...
     
    // In Java
    System.out.println("ILOG_LICENSE_FILE='" + System.getenv("ILOG_LICENSE_FILE") + "'");
    IloCplex cplex = new IloCplex();
    ...
    

    and check if the result is the license file you have for the AI version?

    ILOG_LICENSE_FILE='C:\ILOG\ILM\access.ilm'

    Content of the access.ilm

    LICENSE IBM ILOG Optimization Suite for Academic Initiative

    EVAL CPLEX 12.000 => it is a correct version?
