Option 1: If your Documents folder is located on a network drive 

Launch Tableau Prep using your default user credentials, rather than as an administrator. 

Option 2: If your Documents folder may have moved

  1. In Windows Explorer, right-click your Documents folder 
  2. Select Properties > Location > Reset to Default  


Either the Windows Documents folder has been moved, or is missing, or it is located on a mapped network drive.
