If the Web Setup Wizard stops, informs you that the installation is incomplete, but does not display an error in the console log, the likely cause is you did not run composer install from the <magento_root>/setup directory. The entire message is Installation is incomplete. Check the console log for errors before trying again.

Description

You must run composer install from both the <magento_root> and <magento_root>/setup directories before installer.

Suggestion

Run composer install from both of the preceding directories and try the installation again.
