Issue

When connecting to a data source from Tableau Desktop, the following error might occur:

Internal Error - An unexpected error occurred and the operation could not be completed

Environment

  • Tableau Desktop
  • Any data source

Resolution

  1. Verify that Tableau Desktop was installed using administrator privileges.
  2. Work with your IT team to grant the user account administrator rights to the C: drive, specifically to the AppData folder.

Cause

Tableau Desktop is unable to create temp tables when opening a data source, because access to the TableauTemp directory, in the AppData folder, is denied for the Windows account being used.
