Wait until the installation process is finished.<\/p>\n
Once the installation is complete, click Next to continue to the final setup stage.<\/p>\n
Step 7: Create the Odoo Database<\/h3>\n
After installation, the Odoo Database Manager will open.<\/p>\n

You will need to provide information such as:<\/p>\n
\n- Master Password<\/li>\n
- Database Name<\/li>\n
- Administrator Email<\/li>\n
- Administrator Password<\/li>\n<\/ul>\n
The master password is used to manage Odoo databases, while the administrator credentials are used to access the Odoo application.<\/p>\n
Enter the required information and select Create Database.<\/p>\n
Step 8: Log In to Odoo 20<\/h3>\n
Once the database has been created, Odoo will take you to the login page.<\/p>\n
Enter the administrator email and password created during the database setup.<\/p>\n
Click Login to access your Odoo 20 environment.<\/p>\n
After successful login, you will be taken to the Odoo dashboard.<\/p>\n

- Accounting<\/li>\n
- Project Management<\/li>\n

<\/strong><\/p>\nCommon Odoo 20 Installation Issues on Windows<\/p>\n
Although the Windows installer simplifies the installation process, users may encounter configuration problems.<\/p>\n
PostgreSQL connection issues <\/strong><\/p>\nIf Odoo cannot connect to PostgreSQL, check the database host, port, username, and password entered during configuration.<\/p>\n
Installation permission problems <\/strong><\/p>\nIf Windows prevents the installer from making changes, make sure you are using an account with the required installation permissions.<\/p>\n
Incorrect installation path <\/strong><\/p>\nIf you selected a custom installation directory, verify that the selected folder is accessible and has sufficient storage space.<\/p>\n
Odoo does not open after installation <\/strong><\/p>\nCheck whether the Odoo service has started correctly and verify the installation configuration before attempting to restart the application.<\/p>\n
For source-based installations, Odoo’s documentation explains that the server can be started on Windows and accessed through http:\/\/localhost:8069.<\/p>\n
