Odoo 18 Windows installation is a crucial skill for anyone looking to leverage the power of Odoo’s ERP system on a Windows 11 machine. Whether you’re a business owner, developer, or IT enthusiast, this comprehensive tutorial will walk you through every step of the process, ensuring a smooth and successful setup.
Why Choose Odoo 18 on Windows?
Odoo 18 is packed with new features and improvements, making it a top choice for businesses seeking a flexible, open-source ERP solution. Installing Odoo 18 on Windows 11 allows you to take advantage of the latest technology while working in a familiar environment. With the right approach, Odoo 18 Windows installation can be quick, efficient, and hassle-free.
Step 1: Preparing for Odoo 18 Windows Installation
Before you begin, make sure your Windows 11 system is up to date. This helps prevent compatibility issues during the installation process. It’s also a good idea to temporarily disable Windows Defender or any third-party antivirus software, as these can sometimes block the installation of new applications.
Checklist:
- Windows 11 updated
- Sufficient disk space (at least 5GB free)
- Administrator access
- Internet connection
Step 2: Downloading the Odoo 18 Installer
The first step in your Odoo 18 Windows installation journey is to download the official Odoo 18 installer. Visit the Odoo Downloads page and select the Windows version. Make sure to choose the latest Odoo 18 Community Edition for the best experience.
After downloading, locate the installer file (usually ending in .exe) in your Downloads folder.
Step 3: Running the Odoo 18 Installer
Double-click the installer to begin. You may be prompted by Windows to allow the app to make changes—click “Yes” to proceed.
Follow the on-screen instructions:
- Click “Next” to continue
- Accept the license agreement
- Choose the installation type (Odoo Server and PostgreSQL if you don’t have PostgreSQL installed)
Tip: If you already have PostgreSQL on your system, you can select “Odoo Server Only” to avoid duplicate installations.
Step 4: Configuring PostgreSQL for Odoo 18
PostgreSQL is the database engine that powers Odoo. During the Odoo 18 Windows installation, you’ll be asked to set a username and password for PostgreSQL. For simplicity, you can use “odoo18” for both, but make sure to remember these credentials for future use.
Leave the default host, port, and other settings unless you have specific requirements.
Step 5: Choosing the Installation Directory
When prompted, select the directory where you want to install Odoo 18. For best results, avoid installing Odoo in the “Program Files” folder, as Windows security settings can interfere with database creation. Instead, create a new folder on your C:, D:, or E: drive (e.g., C:\Odoo18).
Step 6: Completing the Odoo 18 Windows Installation
Click “Install” and wait for the process to complete. This may take several minutes. Once finished, check the option to launch Odoo immediately and click “Finish.” Your default browser should open automatically, displaying the Odoo setup page at http://localhost:8069.
Step 7: Initial Odoo 18 Configuration
On your first visit to the Odoo web interface, you’ll be prompted to create a new database. Enter a database name, your email, and a strong password. Click “Create Database” to finish the setup.
Congratulations! You’ve completed the Odoo 18 Windows installation and are ready to start exploring Odoo’s powerful features.
Step 8: Setting Up Developer Mode
If you plan to develop custom modules or make advanced configurations, you’ll need to enable Developer Mode. In Odoo, go to “Settings” and click “Activate the Developer Mode.” This unlocks additional menus and options for advanced users.
Step 9: Registering Odoo in Environment Variables
For command-line access and custom development, it’s helpful to add Odoo’s installation path to your system’s environment variables.
How to do it:
- Open Windows Search and type “Environment Variables.”
- Click “Edit the system environment variables.”
- In the System Properties window, click “Environment Variables.”
- Under “System variables,” find and select “Path,” then click “Edit.”
- Click “New” and paste the path to your Odoo 18 installation (e.g.,
C:\Odoo18\server). - Click “OK” to save.
This step ensures you can run Odoo commands from any terminal window.
Step 10: Running Odoo 18 from the Command Line
To start Odoo 18 using the command line:
- Open Command Prompt (CMD).
- Navigate to your Odoo installation directory.
- Run the command:
python odoo-bin- Open your browser and go to
http://localhost:8069to access Odoo.
This method is especially useful for developers and advanced users.
Step 11: Installing and Using Odoo Addons
Odoo’s real power comes from its modularity. You can install additional modules (addons) to extend functionality. To add custom modules:
- Place your module folder in the
addonsdirectory inside your Odoo installation. - Restart Odoo and update the app list from the Odoo interface.
