Tableau Extract

Dear Community

when I'm trying to write an Tableau Extract as a "tde"-file with the "Write Tableau Extract" Operator, I'm always receiving the same error "Could not load Tableau Extract API Library". I have Tableau version 2019.4

FYI, I have installed and configured the following:

1. From this site - https://help.tableau.com/current/api/sdk/en-us/SDK/tableau_sdk_installing.htm - I have installed the "Visual C++ Redistributable Packages for Visual Studio 2013", also known as the "Visual C++ runtime library"
2. From the same site I have downloaded this ZIP-file "Tableau SDK for C/C++/Java (64-bit)", in order to have the SDK folder (not the new API) and therefore eventually the possibility to create the extract with the "tde"-format.
3. Afterwards, I have extracted the ZIP-file from point 2 and placed it under the the same folder and same name, as in the description from RM documentation. "C:\Program Files\Tableau Data Extract API"
4. In the next step, I have searched for the Environment Variables. There I have found under system variables the name "path". Under this "path" I have added the following - ;C:\Program Files\Tableau Data Extract API\bin - as the second entry. 
5. The last step, was to create under each system variables and user variables two complete new entries, so four new entries. All of them received the same location - C:\Users\Dominic\Documents -. While two of the new entries received the following name - TAB_SDK_TMPDIR - and the other two received - TAB_SDK_LOGDIR -.

Could someone please explain me the mistake I've made? Also in RM Studio, within the Tableau Operator, I do not receive the possibility to select the "tde"-format, but just the "hyper"-format. 

Thank you very much in advance.
