# Install the AV.io HD+ Config tool

You may install AV.io Config on the same computer(s) where you use AV.io HD+, or only on one computer for configuration. All firmware updates and settings changes are saved to the device and work without any software installed on the computer. For settings to persist after power cycling, please allow 5 seconds before disconnecting or restarting device. Only Windows supports the configuration tool. If you are using any other OS and want to use the configuration tool, you will need to do so using a windows computer.

To install the AV.io HD+ Config tool, follow the directions below for your computer's operating system.

**Windows**
