I've downloaded the Tableau Extract API (64 bit, same as RM) and extracted it to disk. I've also added the \bin to my PATH so it should be working but does not.

Hello @bobpeers
Can you check if you had the Tableau API downloaded from here http://www.tableau.com/data-extract-api
and not the new Tableau SDK
Hi,
I downloaded and indstalled the Tableau Data Extract API from the Tableau website and added the path to the bin folder to my path as shown in the images. I get the error shown in the screenshot.
thanks,
Bob
Hi,
I have fixed this issue myself. It's because you can add the path to the \bin folder in either user or system environment PATHs, you must add it to the system PATH as adding only to the user PATH does not work. I think the documentation should be updated to point this out.
best regards,
Bob

hi, i have the same problem. i followed your instuction already but it didn't work. please help me.
Same here, din't work for me too..tried the solution mentioned above still it dint works..
The frustration though lol
I also cannot get Tableau Writer to work after following instructions exactly. Says there are missing Tableau DLLs
Done, thank you.
But still weird to know that cannot use Tableau SDK instead of Data Extract API, as i know, Data Extract API was duplicate to Tableau SDK.

You're right, this is exactly the situation right now. There were some changes made on the Tableau side when data extraction API has been moved to the new SDK package - some dll files are no longer included. We will see how this can be better supported in the future.
Meanwhile please download the package applicable for your operation system from here
Thank you, Great idea and helped me resolved the same issue!
