What is could not initialize HTML5 browser?

vgpowered

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?

Hi @vgpowered ,

as we write on our requierements page: https://docs.rapidminer.com/latest/studio/installation/system-requirements.html we don't support win XP anymore. While I am not sure if this is the problem, it could cause it. I am checking internally.

You can by the way still activate the old charts in the settings:

This would be at least a work around for now.

Hi,

In this particular case, you would see some additional log entries that tells you what's wrong when you start Studio from the RapidMiner Studio.bat file.
But, as Martin has already pointed out, Windows XP is NOT on our supported Operating System list. And it so happens that the new HTML5 visualizations require a Chromium browser, which does not support Windows XP. So that's why you're seeing this. There is unfortunately nothing your or we can do about it, except drop the mightily outdated Win XP..

Regards,
Marco

Hi @vgpowered,

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,

Rodrigo.

Hi @vgpowered

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

Are you updated to the latest release version?

vgpowered

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.

Same problem with the latest ubuntu.

I have same problem with Ubuntu. I update my RM to last version and then the visualization had this error.

Hi,

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.
