# Get and Install Qt with Qt Online Installer

Qt Online Installer lets you install only the modules and tools you need to develop for a specific desktop platform and deploy your applications to desktop platforms, mobile devices, embedded systems, or MCUs.

To install Qt, complete the instructions on this page or take the How to install Qt course.

## Before you start

Before you start the installation:

- Create an account at Qt Account.
- Ensure that your platform is supported, see Supported Platforms.

## Install

1. On Qt Account, go to Downloads and select Qt Online Installer for your operating system.
2. Run Qt Online Installer.
3. Select the components that you want to install and follow the instructions to complete the installation.

   Note the following:

   - The available selection of components in Qt Online Installer depends on your license.
   - You can always install, uninstall, and update modules and components after the installation with Qt Maintenance Tool (included in every Qt installation).

See the following table to find examples of which components to install depending on your target platforms.
