  • Tableau Desktop
  • Tableau Prep
  • Tableau Reader
  • Tableau Server
  • Windows
  • Visual C++ Redistributable 2017
  • Visual Studio 2017


  1. Uninstall Visual C++ Redistributable 2017 
  2. Redo the Tableau installer steps applicable
  3. Reinstall Visual C++ Redistributable 2017
NOTE: If the above does not work, please verify in Control Panel > Programs & Features that Microsoft Visual C++ Redistributable 2017 has been uninstalled. Also verify at the C:/ drive at the directory for Tableau temp files. If Visual C++ 2018 still is at either location, uninstall Visual C++ again and reboot the computer. Then proceed to reinstall the Tableau packaged executable.

Once Tableau has successfully installed, reinstalling the Visual C++ Redistributable 2017 should be fine. Latest builds can be found here:


When Tableau is installed, part of the installation is VC_redist for 2015.
VC_redist for 2017 will not allow an earlier version of VC_redist to be installed, causing the installation of Tableau to fail.
