# Download If you already have a Java JRE installed level 1.7 or higher (and set in your environment variables) you can [download](http://www.ortussolutions.com/products/commandbox#download) the non-JRE version for your Operating System.

Below you will find the way to get the latest stable and bleeding edge releases. Please also note that in our [installation](https://commandbox.ortusbooks.com/4.4.0/setup/installation) page you will find much more detail information on how to install CommandBox with modern Operating System package managers as well. > **Info** The non-JRE versions are all around 35MB in size, while the embedded JRE versions will go up to 90MB in size. \ Below you can see an image of the available downloads from the Ortus Solutions [download](http://www.ortussolutions.com/products/commandbox#download) page: ![](https://37055082-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LA-UVvV3_TgzQyCXMWK%2F-LA-UZwfeRKM1kVIIYOh%2F-LA-UgovWjqe-6C4Sysq%2Fversions.png?generation=1523647969184859\&alt=media) ## Stable Release Stable versions of CommandBox can be downloaded from the downloads section of our product page. ## Bleeding Edge We use a Jenkins integration server to automate our builds. You can download a bleeding-edge version of CommandBox directly from our integration server here: > **Info** Keep in mind, bleeding edge builds may contain experimental features that are likely to change or bugs. ## Auto Updates Another way to get the bleeding edge version of CommandBox is to install the stable version and run our `upgrade` command using the **latest** flag. [Upgrade API docs](http://apidocs.ortussolutions.com/commandbox/current/index.html?commandbox/system/modules/system-commands/commands/upgrade.html). ```bash upgrade --latest ``` > **Info** Please note that the upgrade command will not update the main CommandBox binary. If there are major updates or you get a message about updating the binary, you will need to download the latest binary and re-install it.
