Hello.
I already read the answer to this question posted in February 2019. But I´m still having problems with this.
My pc fits the RapidMiner studio system requirements.

I´m processing some data in order to visualize a correlation matrix. But when I click in "Matrix Visualization" the message "could not initialize HTML5 browser" appears.
Please, how can I solve this?

Best Regards,
Érika

    Varun,
    Thanks for your answer.
    The log error message is
    "PM WARNING: Failed to initialize HTML5 chart rendering
    PM SEVERE: Failed to create HTML5 browser! "

    But I still don´t know how to solve this problem.

    BG,
    Erika

    Can you inform which version of Java you were using (version and 32 or 64 bit) and also windows version (64 or 32 bit)? 

    @Marco_Boeck might suggest something on this

    In the meantime, you can use the legacy charts as mentioned in below thread.

    Hi,

    1. What operating system are you using?
    2. What does your USER_HOME/.RapidMiner/rapidminer-studio.log file say? It does contain more information about the cause of the issue.
    As varunm1 mentioned, you can use the old charts for the time being. (The matrix HTML5 visualization itself is unfortunately also displaying the wrong chart until 9.3 due to a bug :( )

    Regards,
    Marco

    Hello guys,
    My Windows version is "7 home basic" 64bits.
    However I didn´t get to apply the solutions you gave me.
    So,I chose "update" on the Program files --> RapidMiner --> RapidMiner Studio.
    Finaly I reinitialized the system.

    I am far away from being an expert in this area, so I really don´t know what exactly happened but this problem was "solved"!
    I am happy I can visualize the RM charts I am working with.

    Thanks for all your time and attention,
    best regards

    Erika
