Resolved following these steps:
- Rollback installation until initial page and choose remove mysql server
- Uninstall from add/remove programs mysql community installer
- reboot
- install version mysql-installer-web-community-5.7.22.1 and select update when it asks.
- done

Answer 2

The only way to get rid of this error is by allowing MySQL Installer to update when it prompts to do so at the beginning of the installation. Please note that you will get this error if you didn't allow the installer to update.

Updating lower_case_table_names = 0 in my.ini doesn't fix this because MySql will re-initialize it to 0.0 everytime before running the scripts.

If you didn't allow updates, you will need to uninstall all components of MySql and run the installer again and let it update.
