KNIME 3.2 Tableau Node dependancy error

Question

I am getting a different error from this post (KNIME 3.2 Tableau Node error). I believe my problem precedes his. I suspect my problem is in setting up my dependencies and PATH variables.

• I have downloaded the Tableau SDK, and placed it both in the KNIME Workspace, and in Tableau's program files. I have configured the linked resources page of the KNIME to point to each file individually and to the bin directory.

• In addition, I have edited the Windows System variable PATH and added in the new \BIN\ directory;
• I have also downloaded the Visual C++ Redistributable Packages for Visual Studio 2013, the 32 bit version I found from here:
  https://www.microsoft.com/en-us/download/details.aspx?id=40784

When I execute I first get a library not found. Then on subsequent executions I get the error "Execute failed: Could not initialize class com.tableausoftware.extract.ExtractAPI"

Does anyone know how to properly set up KNIME's environment to successfully use the Tableau connector?

Answer 1

Okay here are the steps I used in order.

• Download the Java version of the Tableau SDK for Windows: https://onlinehelp.tableau.com/current/api/sdk/en-us/help.htm#SDK/tableau_sdk_installing.htm%3FTocPath%3D_____3

• Unzip that file into a directory called SDK in the workspace you are using. For me this was C:\Users\<'user name'>\knime-workspace\

• Update environment variables for "Path" on your system and in KNIME add a linked folder resource (Preferences -> Workspace -> Linked Resources) Point both towards the \bin\ sub-directory.

• THEN installed the "Microsoft Visual Basic 2013 Redistributables" file.
