Patches

Please note: The following patches are necessary for the previous version RapidMiner 4.0 only. RapidMiner 4.1beta has these patches already integrated.

A small bug in RapidMiner 4.0 prevents the process wizard and the building blocks from working correctly. Furthermore, the Weka library was added to the recommended free non-GPL version by accident. Windows users should download and executate the file rapidminer-patch-4.0.0.1.exe (70 kb) after the installation of RapidMiner. This will automatically install the patch at the correct position.

Users of other platforms or of the GPL version have to perform these three simple steps:

1. Download the file rapidminer-patch-4.0.0.1.zip (7 kb)
2. Unzip the downloaded file in the main directory of RapidMiner
3. Overwrite the template files into the directory etc/templates and etc/buildingblocks of your RapidMiner installation directory, e.g. into C:\Program Files\RapidMiner\RapidMiner-4.0\etc\.... Users of the non-GPL version: Please make also sure that you remove the file lib/weka.jar.
