  <p>Thank you all for the answers.  I have set up my test local environment with a new install of joomla 3.9.22 and was successful in installing Civicrm.</p>
  <p>On the production environment, I downgraded to php 7.3 and applied the suggested patch to the joomla 3.9.23.  After proceeding with the installation of civicrm, I am getting a different error message:</p>

Comments.Text: Welcome to SE!  php 7.4 is not fully supported - switch to 7.3  Sounds like you have the files in place but the installation has failed if you have no db tables.  Do the log files show errors from the installation process?

Comments.Text: I'm having the same issue on Joomla 3.9.23. Succeeded on Joomla 3.9.22 in our test environment so I suspect it's something about CiviCRM and Joomla 3.9.23. (Our test and prod environment are otherwise identical, incl. PHP, MySQL versions, etc.)

  Joomla version 3.9.23 introduced an issue: unzipping an install file with several zips inside itself won't work. This causes the behavior you describe.
  In the next version this issue will be solved. You solve the issue now by manually installing a patch made by Yootheme, which can be found here:
