My team is evaluating CloverDx 5.5 on Windows Server 2016 and would like to use it to build Tableau Hyper files. I think I followed the instructions but I get an error at runtime.

I downloaded and extracted the Hyper SDK from Tableau and unpacked it to a directory:  
C:\Prograp Files\Tableau\extractapi-x64-2019-2-6

As per the instructions, I added the path to the hyper directory under bin to the system-wide %PATH%  
C:\Program Files\Tableau\extractapi-x64-2019-2-6\bin\hyper

When running a simple graph using the Tableau component, I get the following error:

> Graph configuration is invalid.  
> Issue in component [TableauWriter:TABLEAU\_WRITER]  
> Unable to initialize Tableau native libraries. Make sure they are installed and configured in PATH environment variable (see component docs). Underlying error:  
> java.lang.NoClassDefFoundError: Could not initialize class com.tableausoftware.common.Collation

Some questions:

1: Does the Tableau Hyper SDK need to be installed in a particular location?  
2: Do other environment parameters need to be set?  
3: We also have Tableau and Tableau server installed on the machine. Are these installations interfering with the operation of the component somehow?

Any guidance would be appreciated.

Hi Paul,

My colleague Kevin answered your question directly but I am going to post his answer here in case anyone else has the same issue and is looking for an answer.

Best regards,

_Hi Paul,_

_I recreated this issue. I think the correct setting for path is …/bin instead of …/bin/hyper._  
_Can you remove the /hyper from your path setting and try again?_  
_Per your forum entry I think that would make your path entry_  
_C:\Program Files\Tableau\extractapi-x64-2019-2-6\bin_
