My Rapidminer Studio always shows "Could not initialize HTML5 browser. See log for details." when showing "Visualizations".

The log window has a message like: "PM SEVERE: Failes to create HTML5 browser!"
What's the problem?

    What version of RapidMiner Studio are you using, on what kind of operating system and what Java version are you using? And when did you notice this first time?

    All the best,

    Hi @vgpowered

    There was that exact problem with version 9.2 betahttps://community.rapidminer.com/discussion/54935/visualizations-stopped-working-in-rm-9-2-beta#latest

    Are you updated to the latest release version?

    Thanks. We are using the just downloaded version 9.2 rev 461351. It was the only version to download. The operating systema is Windows XP SP3. The problem hapens every time you want to use "Visualizations". How to know what Java version? The javaw.exe executing is the one installed in the "Rapidminer Studio\jre\bin" folder.

    When you start Studio on some Linux distributions, you might see a "next missing dependency: xyz" log entry in the Terminal during Studio startup. You need to install those missing dependencies manually. In your case, my bet would be "next missing dependency: browsercore64 => libgconf-2.so.4". You can install that missing dependency by running "sudo apt install libgconf-2-4".

    I'm having a similar issue to the question posted - getting a similar error message ("AM SEVERE: Failed to create HTML5 browser!") and not able to use visualizations/charts.  I have a Mac and OS X Version 10.9.5.  Do you know how I can fix?

    I have the same problem in Mac OS X 10.11.6 El Capitan. My RM installed version is 9.2. How can I fix this issue?

    hi @keyopen there is an artful dance that happens between Mac OS X and Java applications, and RapidMiner gets caught in the middle of this dance. You are using Mac OS X 10.11.xx which is three versions behind the current one (10.14.3 Mojave according to my computer) - this is strongly discouraged. Hence recommended fix is to upgrade to most recent version of Mac OS X.
