Could not initialize HTML5 Browser! See log for details

erikvaningen

Most likely this is due to our organizations security settings. I am on W10, RapidMiner 9.3.001

What could I do to overcome this problem?

Hi,

I have 2 requests:

1. Could you please provide me with the complete rapidminer-studio.log file after a fresh start of Studio until the point the problem appears? You can find it in the "C:\Users\yourUsername\.RapidMiner" folder.
2. Could you please also provide me with the 3 browser log files (browser-chromium.log, browser-general.log, browser-ipc.log) which you can find in the "C:\Users\yourUsername\.RapidMiner\internal cache\browser" folder.
   

You can send them to me via a private message if you don't want to make them publically available.

Regards,
Marco
