  • 1.  How to download version 22.12 of cplex？

    Posted 06/30/25 10:36 AM

    I downloaded version 22.12 of cplex through academic access on April 7th, but today I couldn't find the download link and could only find version 22.11.

    However, this version does not correspond to the Python API version installed through conda. Can someone help me find the download method

    The version 22.1.2 is available in academic initiative. You need to go to the Text tab in search options and just type "cplex", the 22.1.2 will appear in the list.

    The link is https://academic.ibm.com/a2mt/email-auth#/ 
    Then click on "Data science" and then on "ILOG CPLEX Optimization Studio".

    Thanks but I have been there. After logging in and selecting data science/cplex, I get an error message

    Can't open the web page. Trying with two different browsers (Chrome and Safari), tried in incognito mode, turned off ad blockers. Nothing help...

    I've tried again using Chrome and can access without any problem to CPLEX releases. 
    The error you get might be due to your Chrome installation or your computer configuration and state.

    Has this issue/problem been solved?

    I cannot download ILOG/CPLEX either.

    The Download link is broken.

    I downloaded version 22.12, 24th september. I was connected but it was hard to find last version. File downloaded was COSCE2212_WIN64.exe. Then, after executing cplex studio optimization, there was limit.

    I retryed this evening 29th september, I choiced academic menu and cplex version was 22.11, not 22.12. I downloaded cplex_studio2211.win_x86_64.exe. I found your message and I encountered same issue. After executing cplex studio optimization 22.11, there was no limits
