Qt Installation Program
You can use the Qt 5 installation program to install the following components:
- Qt libraries, prebuilt for a particular development platform (operating system and compiler)
- Qt Creator integrated development environment (IDE)
- Basic development tools, prebuilt for a particular development platform
- Documentation
- Qt in source code form (needed only if you want to build the framework and tools yourself)
Install Qt libraries to develop or run applications that need the Qt runtimes or to try out example applications built with Qt.
Qt Creator is designed to make Qt development easier, but you can also use a 3rd party IDE (such as MS Visual Studio), or just an editor and command line, in addition to basic Qt development tools (Qt Designer, Qt Assistant, qmlscene, and so on).
Installing Qt 5
You can download Qt 5 from http://qt-project.org/downloads. The site provides download links for all supported development platforms. The Qt Enterprise packages are available from the Try Qt Enterprise page.
Start the installation program like any executable on the development platform. On Linux, you might first have to make the installation program executable.
Select the components that you want to install and follow the instructions of the installation program to complete the installation.
Use the Maintenance Tool under <install_dir> to remove all installed components.
Platform Installers
Several installers exist for targeting different platforms. The table below summarizes the available installers.

| Android Windows 32-bit host installer | x86 and ARMv7 |
Starting Development Tools
You can start Qt Creator directly after the installation by selecting the option on the last page of the installation program. You can start most of the development tools, such as GUI designers, compilers, and debuggers directly from Qt Creator. You can also access the installed documentation and example applications from Qt Creator.
In addition to Qt Creator, the installer is able to install the full set of Qt tools, for example:
- Qt Assistant, the Qt documentation reader
- Qt QML Scene, the viewer for Qt Quick 2 files
- Qt QML Viewer, the viewer for Qt Quick 1 files
- Qt Designer, the GUI designer for Qt widgets-based applications
- Qt Linguist, the language translation manager tool
The development tools are located in the directory <install_dir>/<version>/<compiler>/bin. For Windows, the MinGW toolchain is placed in <install_dir>\Tools. You can run them from Qt Creator or from the command line. You can also launch some of them as standalone applications.
Running Example Applications
You can open most example applications in the Qt Creator Welcome mode to build and run them. Additional examples can be opened by browsing <install_dir>/<version>/<compiler>/examples.
