How to Install Odoo 18 on Windows?

There are two ways to setup Odoo in the Windows system:

• Installation Using Packaged Installer.
• Installation with Odoo Source Code.

We will concentrate on the installation procedure using the Odoo 18 source code in this article.

1. Odoo installation using a packaged installer

   Odoo provides Packaged Installer which automatically installs all the dependencies. It is recommended if you do not need code-level customization. You can simply download Odoo Packaged Installer and proceed with the installation.

2. Installing Odoo in Windows using Odoo source code

   If you are a developer, it is recommended to set up Odoo using source code as it offers flexibility if you wish to customize from code. For installation, Git is a prerequisite. If Git is not installed, you can download Git now.

How do I install Odoo 18 on Windows?

To install Odoo, we need the Odoo Source Code. We can clone Odoo’s official repository from GitHub.

1. Download Odoo Source Code

   1. Open the command prompt.
   2. Go to the directory where you want to take a clone of Odoo’s source code.
   3. Take a clone using the command (HTTPS).
      1. git clone https://github.com/odoo/odoo --single-branch -b 18.0

         

         (Fig. 1: Clone Odoo Source Code from the command prompt)

2. Install Python (3.10 or a newer version)

   By default, Windows doesn’t include pre-installed Python. So, we must install preferably the latest version of Python.
    

   1. Download the Python installer from www.python.org/downloads/.

      

      (Fig. 2: On the official website to download Python)

   2. Double-click and run the downloaded file.
   3. In the installation wizard, check the checkbox Add python.exe to PATH and then Install Now.
       
   4. If you have checked the checkbox Add python.exe to PATH, it will automatically set the path, and it will show the notification of successful installation.

      

      (Fig. 3: Python Installer)

   5. After successful installation, confirm the version of the recently installed Python, just to make sure that Python is executable from the command prompt.

3. Install PostgreSQL (16 or newer version)

   1. Visit the PostgreSQL download website and click on Download the Installer.

      
       

      (Fig. 5: PostgreSQL Website)

   
   
   2. You will be redirected to the EDB website.
   3. Click on the download button beside the PostgreSQL version greater than or equal to 16. Follow the simple prompts as shown below in the pictures.

      (Fig. 16: PostgreSQL Installer)

   7. Add PostgreSQL path in environment variables (C:\Program Files\PostgreSQL;<version;>\bin).

 

1. Create a new PostgreSQL user

   Although there is already one PostgreSQL user, Odoo does not allow a user to connect due to security reasons. We will need to create a new user. For example, “Odoo”, which we will use in the future to start the Odoo server.
   1. Go to pgAdmin.

      

      (Fig. 17: pgAdmin – Set Master Password)

   2. When prompted, enter the PostgreSQL password (the password that we have set during installation).

      

      (Fig. 18: pgAdmin – Connect to the server using Postgres User Password)

   3. Double-click the PostgreSQL server to establish a connection.
   4. Go to toolbar > Object > Create > Login/Group Roles.

      

      (Fig. 19: pgAdmin – Create Role)

   5. Provide the appropriate username (use Odoo) in the field “Role Name”.

      

      (Fig. 20: pgAdmin – Create Role – Set Name)

      

      (Fig. 21: pgAdmin – Create Role – Set Password)

   
   
   6. Inside the Definition tab, type in a new password.
   7. Then go to the Privileges tab, toggle the Can log in and Create Database to set them to true, and then Click the Save button.

      

      (Fig. 22: pgAdmin – Create Role – Set Privileges)

2. Install Dependent Libraries

   In the command prompt, go to the recently cloned Odoo repo where the requirements.txt file is located and run the commands:

   1. pip install setuptools wheel
   2. pip install -r requirements.txt

   

   (Fig. 23: Command Prompt – Install setuptools and wheel)

    

   

   (Fig. 24: Command Prompt – Install all libraries from requirements.txt)

    

3. Download and install wkhtmltopdf

   Steps to download and install wkhtmltopdf:

   1. Go to https://wkhtmltopdf.org/downloads.html and download the executable file.
       

      

      (Fig. 25: wkhtmltopdf website – Download Installer)
       

   2. Double-click to run the executable file and the pop-up will appear for permission, click “Yes”.

      

      (Fig. 26: wkhtmltopdf Installer)

   3. Then the installation wizard will open, here we have to click “Next” until the installation process is completed, and finally, click “Close”.

      

      (Fig. 27: wkhtmltopdf Installer)

      

      (Fig. 28: wkhtmltopdf Installer)

4. Configure Odoo & Start the Server

   1. Open the command prompt, visit the Odoo directory, and locate the Odoo-bin file.
   2. Run the command:
      1. python odoo-bin -r db_user -w db_password --addons-path=addons -d demo_db

       

      

      (Fig. 29: Command Prompt – Start Odoo Server)

   3. Here db_user is the newly created database user (choose it Odoo) and db_password will be its password (Odoo).
   4. Go to the browser and in the address bar, type localhost:8069 and hit enter.
   5. In the login screen, enter your email (admin) and password (admin) and Hit “Login”.
