To run and use **RabbitMQ** on Windows, you first need to **download and install Erlang**.

**Why is Erlang required for RabbitMQ?**

RabbitMQ is built on **Erlang**, which provides the underlying runtime and messaging capabilities. Since RabbitMQ relies on **Erlang's Open Telecom Platform (OTP)** for scalability, concurrency, and fault tolerance, it cannot function without it. Installing Erlang ensures that RabbitMQ runs smoothly on **Windows** or any other system.

Open any browser and search "**erlang download**"

Open the first link with the address - [erlang.org/downloads](//erlang.org/downloads)

**What is Erlang?**

**Erlang** is a **functional, concurrent programming language** and runtime system designed for **highly scalable, distributed, and fault-tolerant systems**. Originally developed by **Ericsson** for telecom applications, it is now widely used in **messaging systems, real-time applications, and distributed computing**.

Erlang’s **Open Telecom Platform (OTP)** provides powerful tools for **concurrency, message passing, and fault recovery**, making it essential for applications like **RabbitMQ**, which rely on fast and reliable message processing.

**Erlang Download** page will open. Click on the **dropdown** for the **Windows Installer**, then select and click on the **Download 64-bit Installer** to begin the installation.

**Downloads** wizard will open, select the **Downloads** folder and click on the **Save** button

**Note:** The recorded demo uses **otp_win64_27.3**, but the actual installed version may vary depending on the latest available release at the time of installation.

After downloading **Erlang**, search for **"RabbitMQ download"** in your browser and click on the link with the address [rabbitmq.com/docs/download](//rabbitmq.com/docs/download) to access the official RabbitMQ download page.

**What is RabbitMQ?**

**RabbitMQ** is an open-source **message broker** that enables applications to communicate asynchronously using a **message-queueing system**. It supports multiple messaging protocols, ensuring reliable message delivery, load balancing, and scalability. RabbitMQ is widely used for **distributed systems, microservices, and event-driven architectures**, helping applications process tasks efficiently without direct dependencies. It supports **AMQP (Advanced Message Queuing Protocol)** and integrates with various programming languages and frameworks.

**RabbitMQ Download** page will open. To download RabbitMQ on **Windows**, click on the **Windows Installer** link under the **Installation Guides** section for Windows.

**Install RabbitMQ for Windows** page will open. Scroll down to the **Direct Downloads** section and click on the **Download .exe file** to start the installation.

**Downloads** wizard will open, select the **Downloads** folder and click on the **Save** button

**Note:** The recorded demo uses **rabbitmq-server-4.0.7**, but the actual installed version may vary depending on the latest available release at the time of installation.

Once the download is complete, double-click the downloaded otp_win64_27.3.exe executable file, follow the installation steps, and grant any required permissions when prompted.

**Why do we install Erlang first and RabbitMQ after?**

Erlang must be installed **before** RabbitMQ because **RabbitMQ is built on Erlang** and depends on the **Erlang runtime environment** to function properly. RabbitMQ uses Erlang's **Open Telecom Platform (OTP)** for messaging, concurrency, and fault tolerance. If Erlang is not installed first, RabbitMQ will fail to run since it requires Erlang libraries and runtime support.

After the erlang download is completed, double-click the downloaded rabbitmq-server-4.0.7.exe executable file, follow the installation steps, and grant any required permissions when prompted.

After a while, **RabbitMQ** will be successfully installed on your system.

Congratulations on successfully installing RabbitMQ on Windows and completing this lab!
