For errors using Tableau Desktop:
If you are receiving an error message when attempting to open a workbook downloaded from Lever Talent Intelligence, double check to verify that you have installed the latest version of Tableau Desktop. Workbooks can only be opened in Tableau Desktop version 10.1.3 or newer.
For errors using Tableau Reader:
When opening a workbook downloaded from Tableau Server in Tableau Reader, the following error might occur:
Unknown data source class 'sqlproxy'.
This occurs because the workbook is using a live connection to a data source published to Tableau Server. Tableau Reader cannot open workbooks or .twbx files that use a live connection to data. In order to successfully open a downloaded workbook, extract the data from the data source via Tableau Desktop prior to opening the workbook in Tableau Reader.
