    ssas tabular data source for published workbook - class not registered error

    Alexander Alongi

      I successfully connected to SSAS tabular in Tableau Desktop and created a workbook. I then published the workbook to my Tableau Server with the authentication settings embedded in the workbook. Now, when I access the workbook in tableau server through a web browser, I get the following error:



      • Database error 0x80040154: Class not registered
      • Unable to connect to the server. Check that the server is running and that you have access privileges to the requested database.



      I believe I have downloaded and installed the proper drivers from the tableau driver's page. I know it is not a user access problem, as I have monitored my SQL Server when troubleshooting this issue, and I don't ever see any activity making it to the SQL server from the tableau server. Has anyone successfully published workbooks to tableau server with SQL Server 2012 SSAS Tabular as the data source?
