Visual Analytics Kit for Tableau - installation issues

[sonal_dighe]

Hi,

I'm working on using an Alteryx workflow to publish reports to an internal Tableau server. Attempting to extract the Visual Analytics Kit for Tableau gives me errors with some .DLLs and .EXEs when I try to extract the files in the C:/Program Files folder. The error window screenshot is attached. (I didn't expect this to happen as I do have admin rights on my machine, but anyway.) So I tried to uninstall and re-install the kit on my Desktop. That stopped the error from popping up, but running the workflow gives me a curl.exe error message as "Error: Publish to Data Server (1): Tool #25: Record #1: Tool #1: The external program "curl.exe" returned an error code: -1073741512"

The tool #25 inside the Publih Tableau macro is too obtuse to show what this error code means. Googling it gave back nothing of worth either. I've also tried uninstalling and re-installing Alteryx and the Tableau kit, but keep running into the same problems.

Any help will be appreciated. We're just going round in circles at this point!

Thanks,
Sonal

Hi Sonal,

Someone may be able to respond with what has worked for them, but the following 2 ideas could help you.

The error message is basically saying that it's having trouble running cURL.exe. In order to rule out permission issues, you can try installing the visual analytics kit into your Users directory and then in Alteryx under "Tools > User Settings > Macros (Tab)" add that directory as a repository.

The following link may help you investigate more, http://www.theinformationlab.co.uk/2014/09/10/getting-tableau-server-rest-api/, the relevant part of it being in the comments from Andrew M:

If you get “curl.exe returned an error code: -1073741512?, then test curl.exe from CMD prompt. If that gives “LIBEAY32.dll missing…” error then see http://stackoverflow.com/questions/6534505/how-to-fix-libeay32-dll-was-not-found-error Replacing the provided …Tableau_Samples_InstallMacrosSupporting_Macroscurl.exe with the one from http://www.paehl.com/open_source/?download=curl_741_0_ssl.zipthat includes SSL works fine for me.

Thanks for replying Kane. Unfortunately, that link you shared is where I started from and reached where I'm stuck right now. There are no missing DLLs, from what I can see...

Have you tried replacing the version of curl.exe that comes with the kit (in the Macros/Supporting_Macros folder) with the one linked in Kane's post? If you haven't already, I would recommend giving that a try, as this is a fairly common issue and that usually does the trick to fix it.

Alright. I got the same issues and could finally install without any issues. First thing, try to give admin rights for the folder you are trying to install this, I had to do this. Next thing, I got the dll missing error, then download and install the OpenSSL from this page - https://slproweb.com/products/Win32OpenSSL.html . Make sure that you install Win32 OpenSSL v1.0.2d Light file as it fulfills the dll dependencies. While installing make sure that the DLL installation path is windows directory.  This will solve your issues. 

Note : you have to do all this if you have downloaded visual analytics kit for tableau from Alteryx as they dont have the dependency dlls packed up with their installation file. If you want to avoid all this issues, download the latest version fo the kit from - http://www.theinformationlab.co.uk/att  . This installation file automatically install OpenSSL for you.

 Let us know if you still have any issues.

Make sure you check the option that puts DLLs in the Windows System Directory.
