Due to the manual changes in the Broadcaster’s transcoder code for the CEF integration, updating a Broadcaster via the UI is not possible.  Instead, from the command line you will install the new version of the Broadcaster overtop of the existing version and then use HTML overlay startup script mentioned above again.

### To update the Zixi Broadcaster when CEF Software is already installed:

::::WorkflowBlock
:::WorkflowBlockItem
Download new Broadcaster .tar.xz installer file to the parent directory of the existing Broadcaster installation; typically this is /zixi.
:::

:::WorkflowBlockItem
Stop the Broadcaster process with the following command.

```bash
service zixibc stop
```
:::

:::WorkflowBlockItem
Extract Broadcaster .tar.xz installer file.

```bash
tar xvf zixi_broadcaster-18.6.46249.linux64.tar.xz
```
:::

:::WorkflowBlockItem
This will overwrite the Broadcaster installation directory, but the existing configuration xml files in the installation directory will not be overwritten.
:::

:::WorkflowBlockItem
Change directory to the Broadcaster installation directory, zixi\_broadcaster-linux64/.

```bash
cd ./files
mv ../../zixi_broadcaster-linux64/files/* 
cd ..
```
:::

:::WorkflowBlockItem
Follow **steps 4 through 6 above** to download and install the CEF plug-in software. Be sure to download a new CEF installer that matches the version of the Broadcaster you are installing.
