Installing KNIME Analytics Platform

  1. Go to the download page on the KNIME.com website to start installing KNIME Analytics Platform.

  2. The download page shows three tabs which can be opened individually:

    • Register for Help and Updates: here you can optionally provide some personal information and sign up to our mailing list to receive the latest KNIME news

    • Download KNIME: this is where you can download the software

    • Getting Started: this tab gives you information and links about what you can do after you have installed KNIME Analytics Platform

  3. Now open the Download KNIME tab and click the installation option that fits your operating system. KNIME Analytics Platform can be installed on Windows, Linux, or macOS.

    Notes on the different options for Windows:

    • The Windows installer extracts the compressed installation folder, adds an icon to your desktop, and suggests suitable memory settings.

    • The self-extracting archive simply creates a folder containing the KNIME installation files. You don’t need any software to manage archiving.

    • The zip archive can be downloaded, saved, and extracted in your preferred location on a system to which you have full access rights.

      010 install files

  4. Read and accept the privacy policy and terms and conditions. Then click Download.

  5. Once downloaded, proceed with installing KNIME Analytics Platform:

    • Windows: Run the downloaded installer or self-extracting archive. If you have chosen to download the zip archive instead, unpack it to a location of your choice. Run knime.exe to start KNIME Analytics Platform.

    • Linux: Extract the downloaded tarball to a location of your choice. Run the knime executable to start KNIME Analytics Platform.

    • Mac: Double click the downloaded dmg file and wait for the verification to finish. Then move the KNIME icon to Applications. Double click the KNIME icon in the list of applications to launch KNIME Analytics Platform.

The following operating systems versions are supported:

  • Windows

    • Windows 10, 11

    • Windows Server - 2016, 2019, 2022,

  • Ubuntu 20.04 LTS and 22.04 LTS and derivatives

    • macOS 12: Monterey

    • macOS 13: Ventura

Also check the KNIME Getting Started Guide and the KNIME Analytics Platform User Guide.

Configuration settings and knime.ini file

When installing KNIME Analytics Platform, configuration settings are set to their defaults, and they can later be changed in the knime.ini file. The configuration settings, i.e. options used by the Java Virtual Machine when KNIME Analytics Platform is launched, range from memory settings to system properties required by some extensions.

You can find knime.ini in the installation folder of KNIME Analytics Platform.

On MacOS: To locate knime.ini on MacOS, open Finder and navigate to your installed Applications. Next, right click the KNIME application, select Show Package Contents in the menu, and navigate to Contents → Eclipse.

The knime.ini file can be edited with any plaintext editor, such as Notepad (Windows), TextEdit (MacOS) or gedit (Linux).

Allocating memory in knime.ini file

The entry -Xmx1024m in the knime.ini file specifies how much memory KNIME Analytics Platform is allowed to use. The setting for this value will depend on how much memory is available in your machine. KNIME recommends setting it to approximately one half of your available memory, but you can modify the value based on your needs. For example, if your computer has 16 GB of memory, you might set the entry to -Xmx8192m.

Installing Extensions and Integrations

If you want to add capabilities to KNIME Analytics Platform, you can install extensions and integrations. The available extensions range from free open source extensions and integrations provided by KNIME to free extensions contributed by the community and commercial extensions including novel technology nodes provided by our partners.

The KNIME extensions and integrations developed and maintained by KNIME contain deep learning algorithms provided by Keras, high performance machine learning provided by H2O, big data processing provided by Apache Spark, and scripting provided by Python and R, just to mention a few.

Install extensions from:

  • KNIME Hub:

    • Search for the Extension or Integration you want to install in the search bar

    • Click Extensions on the results page

    • Click the extension you want to install, and from the extension page and drag and drop the squared yellow icon, shown in Figure 2, to the KNIME Analytics Platform. A window will open asking if you want to search and install the extension or integration. Click Yes and follow the instructions.

      Figure 3. Installing Extensions and Integrations from KNIME Analytics Platform

    • Select the extensions you want to install

    • Click Next and follow the instructions

    • Restart KNIME Analytics Platform.

The Install Extensions menu provides the extensions that are available via the update sites you have enabled.

If you encounter issues during the installation of Python based extensions, these might be related to challenges specific to this type of extensions. Find here information about how to troubleshoot these issues.

To uninstall an extension, go to the Help menu in the top right corner of the user interface and select the About KNIME Analytics Platform. In the window that opens click Installation Details. A dialog shown in Figure 4 opens. Now, select the extension that you want to uninstall, and click Uninstall…​.

Updating KNIME Analytics Platform and Extensions

It is good to make sure that you always use the latest version of KNIME Analytics Platform and its extensions.

To do so:

  1. Go to the Menu in the top right corner of the KNIME Analytics Platform.

  2. Select Check for updates. In the dialog that opens, select the available updates you want to install and then click Next.

  3. Proceed by following the instructions. KNIME Analytics Platform has to be restarted in order to apply the updates.

Update Sites

The Update Sites are where KNIME retrieves additional software in the form of extensions as well as updates. To see or edit the available update sites, click Preferences in the top right corner of the user interface. This opens the Preferences dialog. Select Install/Update → Available Software Sites.

Default Update Sites

These four updates sites are provided by KNIME and are always available:

030 update site
Figure 5. Available Update Sites

KNIME Analytics Platform 5.2 Update Site: Provides all extensions and integrations maintained by KNIME: R, Python, H2O Machine Learning, Apache Spark for big data, and many more. Contains KNIME Labs Extensions, which are extensions that are not yet part of the set of stable KNIME extensions because their functionality may not yet be finalized.

Community Extensions (Experimental): Provides additional extensions created by the KNIME community.

KNIME Community Extensions (Trusted): Provides trusted community extensions, i.e. extensions created by the KNIME community, which have been tested for backward compatibility and compliance with KNIME quality standards.

KNIME Partner Update Site 5.2: Provides extensions created by KNIME partners.

KNIME Analytics Platform 5.2 Update Site and KNIME Community Extensions (Trusted) are enabled by default.

Adding External Update Sites

To install extensions that are not part of the above update sites, click Add to manually add the relevant update site, inserting the Name and Location as shown in Figure 6.

030 add update site
Figure 6. Add Update Sites

After adding a new update site you will see it listed in the Available Software Sites. You must now enable it by selecting it from the list.

Adding Local Update Sites

If your working environment has limited internet access or you receive an error message “Proxy Authentication Required” when connecting to a remote update site (provided by a URL), you can install extensions from a local zip file.

  1. Download KNIME update sites as zip files at the following links:

  2. Save the zip file containing the extensions to your local system

  3. Click Preferences in the top right corner of the user interface. This opens the Preferences dialog. Select Install/Update → Available Software Sites and enter the path to the zip file by clicking Add → Archive…​ as shown in Figure 7.

    040 add zip archive
    Figure 7. Adding Update Sites from Zip Archive
    If the same extensions are provided by a URL, you will first have to disable the update site by disabling it in the list.

  4. Now click Apply and Close

    If the same extensions are also provided by a remote update site, you will first have to disable that update site by deselecting its entry in the Available Software Sites dialog and confirming via Apply and Close.

Working with the Nightly Builds

Once a night, a new version of KNIME Analytics Platform is created directly from our development branch. The Nightly Build versions available here provide insight into what’s coming up in the next regular release. However, for real work, always use a version of a standard KNIME release. Also read the following disclaimer before proceeding:

Really, really, really important disclaimer

This is most definitely not production quality code. These nightly builds are what we use internally to validate and test recent developments, so they are not tested as thoroughly as standard KNIME releases. Furthermore new nodes or functionality may change substantially (or disappear entirely) from one build to the next. It’s even possible that workflows you edit or create with nightly builds stop being readable by future (or past) versions…​

These nightlies are a great way to get a sneak peek at what may be coming in the next version of KNIME and provide feedback and suggestions. They are not a particularly safe way to do real work.

Release notes and changelogs (KNIME Analytics Platform 5.2)

Release notes and detailed changelog for v5.2.x releases

KNIME Analytics Platform 5.2.0

Release date: December 06, 2023

Release notes

  • As of KNIME AP 5.1 the “Modern UI” is the new default user interface to view and edit workflows. With 5.2 all relevant functionality has been ported but few remaining features will be added in future releases. This includes:

    • A tree view for the node repository

    • Keyboard navigation for the most prominent features to enhance accessibility via hotkeys within the Modern UI

    • More perspectives in addition to the Starter Perspective

HTML sanitization of JavaScript View nodes and Widget nodes

With the release of 5.2.2 KNIME executors will have HTML sanitization of old JavaScript View nodes and Widget nodes turned on by default. This should ensure that no malicious HTML can be output. It is still possible to achieve the old behaviour by turning the sanitization off globally both for KNIME Hub execution contexts (see intstructions here) and for KNIME Server (see instructions here). For KNIME Server sanitization rules can also be further customized, see KNIME WebPortal Administration Guide.

Interesting nodes to know about:

  • Text Output Widget (legacy): If this is set to output HTML content, it will be sanitized. You can use the new Text View or Image View which have their own sanitization rules internally, but allow certain styling tags or exempt the Text Output Widget from sanitization

  • Image Output Widget (legacy): This will not work with sanitization turned on. Sanitization will strip all SVG tags, leaving in most cases only axis labels and names to be displayed as plain text. Also the workaround here is to use the new Image View or add the node to the exemptions.

  • Generic JavaScript View: This node is now always exempted from global sanitization and have an additional flag (-Djs.core.sanitize.sanitizeGenericJSView ) which is set to true by default for new executors. With this flag enabled all input data to the node (input table and flow variables) will be sanitized.
    This leads to the following behaviour: if a workflow builder set up the node so that just values are displayed by tables and flow variables it might only loose some formatting or simply work as before. However if a script was set up in a way that for example HTML was constructed using the contents of flow variables or JavaScript libraries were injected using flow variables this will now most likely fail. If this is still needed the system property has to be set to false explicitly. Additionally there is a new checkbox in the node to enable/disable this input sanitization. However this will be overwritten if the system property is set to true.

All other (view) nodes might behave differently if a workflow builder tried to customize styling by use of HTML (e.g. in table cells or in tooltips used inside of charts). The effects here should be that either only the styling does not work or some content won’t be visible at all, depending on the context.
