  • Tableau Desktop
  • Tableau Prep
  • Windows 10
  • Visual C++ Redistributable 2017
  • Visual Studio 2017


  1. Uninstall Visual C++ Redistributable 2017 
  2. Reinstall Tableau Desktop or Tableau Prep. 
NOTE: If the above does not work, please verify in Control Panel > Programs & Features that Microsoft Visual C++ Redistributable 2017 has been uninstalled. If it is still there, uninstall it again and reboot the computer. Then try reinstalling Tableau Desktop or Tableau Prep again.


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.
