# Install Qualcomm AI Runtime SDK

> Download and install the Qualcomm AI Runtime (QAIRT) SDK on an Ubuntu 22.04 host computer using direct download or Qualcomm Package Manager.

Qualcomm AI Runtime SDK requires an Ubuntu 22.04 host computer.

<Note>
  If the host computer uses Windows or macOS operating system software,
  install a virtual machine.
  Subsequent steps must be run in the virtual machine running Ubuntu
  22.04 LTS.
</Note>

The Qualcomm AI Runtime SDK workflow has been validated with
Ubuntu 22.04 running on bare metal or inside a Virtual Machine in the
following configurations.

<Note>
  Ubuntu 22.04 running inside a VM on macOS on Arm® architecture isn't supported.
