If you do not have administrative rights on your computer, Internet Explorer (IE) may change Tableau packaged workbooks (.twbx) to zip files when you download them.



  • Tableau Desktop
  • Tableau Server
  • Windows
  • Internet Explorer (IE)


Option 1: Download the workbook from a different browser.

To avoid this issue in the future, download the workbook from a different browser, such as Google Chrome or Mozilla Firefox.

Option 2 : Change the file extension of the downloaded workbook. 

Manually change the file extensions of the downloaded workbook file from ".zip" to ".twbx" to work around the issue. After you have changed the extension to ".twbx," you can open the workbook using Tableau Desktop or Tableau Reader as expected.
