\title Get and Install Qt with \QOI
\brief Downloading and installing the Qt modules and tools that you need.
\QOI gives you the choice of installing only the modules
and tools you need to develop on a particular desktop platform and to run
your applications on one or several desktop platforms, mobile or embedded
devices, or MCUs.
If instead you prefer to build Qt from sources, please see \l{Building Qt
Sources}.
\section1 1. Create a Qt Account
To begin, create a \l{Qt Account}. This account gives you access to a web
portal where you can manage your licenses, as well as access to the forums
and wikis. Also, make sure you read the \l{Qt Licensing} page regarding your
chosen license.
\section1 2. Download \QOI
Go to your Qt account's download page. By selecting the appropriate unified
\QOI for your OS, you can install commercial or open source
versions of Qt, development tools, and other components. \QOI asks for your
Qt account credentials. \QOI retrieves the
license attached to the account from a server and provides a list of
available components corresponding to the license.
\section1 3. Install Qt
To complete the installation, select the components that you want to install
and follow the instructions of the installation program.
You must select at least one Qt version for one platform that you want to
run your applications on. For example, if you have installed Microsoft
Visual Studio 2022 on 64-bit Windows, you could
select \e {MSVC 2022 64-bit} under the Qt version you want to develop with.
However, the easiest way to install Qt for desktop development is to select
the default installation for desktop development. You can install additional
modules later.
\image qtinstallercomponents.webp
If you also want to run your applications on Android devices, for example,
you should select the default installation for mobile development.
The following table contains examples of which components to install
depending on the platforms where you want to run your applications.
\table
\header
\li To Develop For
\li Choose
\row
\li Desktop
\li Default installation for \e {desktop development}.
If you want to use other than the default toolchain, such as
MSVC on Windows, select \e {Custom installation}. Then
select the Qt for the toolchain you want to use.
\row
\li Mobile Devices
\li Default installation for \e {mobile development}.
If you only want to develop for a particular platform, select
\e {Custom installation}. Then select the Qt for the mobile
device platform that you want to run the applications on. For
example, \l{Qt for Android} or \l{Qt for iOS}.
\row
\li Embedded Devices
\li Custom installation, with the necessary Qt modules and toolchains
from the \l{Boot to Qt} section, depending on the types
of devices that you want to run applications on.
\row
\li Android Automotive
\li Custom installation, with \l{Qt for Android Automotive}.
\row
\li Automation
\li Custom installation, with the necessary Qt modules and toolchains
from the \l{Qt for Automation}{Qt for Automation/Qt M2M Protocols}
section, depending on the types of devices that you want to run
applications on.
\row
\li MCUs
\li Custom installation, with \l{Qt for MCUs}.
\endtable
To check the platform requirements, see \l{Supported Platforms}.
\section2 Updating or Removing Components
Once Qt is installed, you can use \e{\QMT} under
\e{<install_dir>} to add components, update, or remove installed
components.
\section2 Getting Help
Evaluation and open source users can get help on the
\l {https://forum.qt.io/}{Qt forum}. See also the
\l {https://wiki.qt.io/Forum_Help}{Help on using the Forum} wiki page.
Non-commercial users can get limited help with the installation process
through \l {https://account.qt.io/support}{Qt support}.
The primary support channel for commercial customers is their
\l {https://account.qt.io/support}{Qt Account}.
\section1 4. Create Applications
After the installation, \l{\QC Documentation}{\QC} opens. You can
use the project wizard templates to start creating applications that run
on your chosen platform.
If you want to design Qt Quick UIs, open \l{Qt Design Studio Manual}
{Qt Design Studio} and use the project wizard templates there.
