What version of Tableau are you using to open the file?
What kind of error message are you receiving?
without any screenshot it's difficult to help you. Please upload the error message. In the meantime, check the Tableau version used to built the workbook.
A screenshot will really help to find a solution.
This is more a guess but if you get "This file was created by a newer version of Tableau", I recommend to upgrade Tableau Desktop.
If that is the error message, the article below may help.
If you get a different error message, please provide the screenshot.
