# Installing on Windows - Quick Start

## Introduction <a href="#toc417629842" id="toc417629842"></a>

This document describes how to run the CAP Console on Windows using the `CAP-Console-12.0.zip` distribution. The example uses Windows Server 2022 Datacenter and OpenJDK 21 LTS.

The installation is designed for a local developer "quick start" environment.

## Check Java installation and version

Running the `java -version` command will either return `java : The term 'java' is not recognized` when no Java installation has been installed and `JAVA_HOME` / `Path` have not been set, or it will display the current Java installation details.

```powershell
PS C:\Users\Administrator> java -version
```

If you need to install Java, download the Microsoft Build of OpenJDK 21 from <https://learn.microsoft.com/en-us/java/openjdk/download> and extract the ZIP to a local directory — this example uses `C:\Users\Administrator\Downloads\`.

Set `JAVA_HOME` and `Path` for the current PowerShell session to confirm the Java version:

```powershell
PS C:\Users\Administrator> $env:JAVA_HOME = "C:\Users\Administrator\Downloads\microsoft-jdk-21.0.6-windows-x64\jdk-21.0.6+7"
PS C:\Users\Administrator> $env:Path += ";$env:JAVA_HOME\bin"
PS C:\Users\Administrator> java -version
openjdk version "21.0.6" 2025-01-21 LTS
OpenJDK Runtime Environment Microsoft-... (build 21.0.6+7-LTS)
OpenJDK 64-Bit Server VM Microsoft-... (build 21.0.6+7-LTS, mixed mode, sharing)
```

The shipped `Tomorrow.bat` in the distribution root looks for a bundled JRE under `.\jre\bin\java.exe` first and falls back to `java` on `PATH`. If you are using a system-installed JDK, ensure `JAVA_HOME` and `Path` are set as above (or set them permanently via *System Properties → Environment Variables*) before launching.

## Launch

Double-click `Tomorrow.bat` in the distribution root to run directly from File Explorer.

{% hint style="info" %}
You may require Administrator privileges if the application fails to launch.
{% endhint %}

Alternatively, run from PowerShell:

```powershell
PS C:\CAP-Console-12.0> .\Tomorrow.bat
```

{% hint style="info" %}
For production deployments, install the Console as a Windows service so it starts automatically on boot. See [Installing as a Windows Service](/cap/product-reference/installation-and-configuration/server-installation.md#installing-as-a-windows-service).
{% endhint %}
