    Desktop 9.3.4 : Class not registered when connecting to SSAS

      We have three desktop application in our office, all of which are Windows 10 machines. Two applications are 9.3 (64bit) and one is 9.3.4 (64bit).

      The two 9.3's have no problem connecting to a SSAS cube, the 9.3.4 one wont connect, claiming the following:


      The drivers necessary to connect to this database are not properly installed

      Database error 0x80040154: Class not registered


      Looking through the forums and help:


      • All machines have Excel 64bit
      • All machines have 64bit Tableau desktop
      • All machines can connect to the cube via Excel
      • All have the same drivers installed from the tableau driver page.


      Has anyone else come across this and what did you do to fix it?
