Configuring Projects
When you install Qt for a target platform, such as Android or QNX, the Qt Online Installer creates kits for the development targets. Select the kits to use in the Configure Projects view when you open a project for the first time. At least one kit must be active. For more information about selecting the initial kit, see Opening Projects.
To maintain the list of active kits for a currently open project, switch to the Projects mode by pressing Ctrl+5.
Activating Kits for a Project
The Build & Run section of the sidebar lists the kits that are compatible with your project. To activate one or more kits, click them.
The list displays kits from Edit > Preferences > Kits. Warning and error icons indicate that the kit configuration is not suitable for the project type. To view the warning and error messages, move the mouse pointer over the kit name.
In the list of kits, you may see entries described as Replacement for <kit-name>. Qt Creator generates them to save your project-specific settings, such as custom build flags or run configuration arguments that would disappear if the corresponding kits were simply removed when you remove Qt versions while updating your Qt installation. You can modify the kit configuration to use a currently installed Qt version and save the kit under a new name.
To modify kit configuration or to add kits to the list or to remove them from it, select Manage Kits. For more information about managing kits, see Adding Kits.
Each kit consists of a set of values that define one environment, such as a device, compiler, and Qt version. For more information, see Adding Qt Versions, Adding Compilers, and Adding Debuggers.
To copy the build and run settings for a kit to another kit, select Copy Steps from Other Kit in the context menu.
To deactivate a kit, select Disable Kit for Project in the context menu.
Note: Deactivating a kit removes all custom build and run settings for the kit.
To import an existing build for the project, select Import Existing Build.
Specifying Settings
To specify build or run settings for a kit, select Build or Run below the kit. For more information, see Specifying Build Settings and Specifying Run Settings.
In addition, you can modify the following global settings for each project:
If you have multiple projects open in Qt Creator, select the project to configure in the list of projects.

QtCreator: No valid kits found
Installed just the IDE on Windows 7. I want to create a Plain C++ Project (Non-QT Project); however I get an error: No valid kits found. When I click on Options->Kits, I see the Desktop (default) kit, and it shows no errors.
Am I getting the error because I didn’t install a Qt library? If so, is there any way I can bypass downloading/installing that and just use the IDE?

Found the issue. Qt Creator wants you to use a compiler listed under one of their Qt libraries. Use the Maintenance Tool to install this.
Go to Tools -> Options. Select Build & Run on left. Open Kits tab. You should have Manual -> Desktop (default) line in list. Choose it. Now select something like Qt 5.5.1 in PATH (qt5) in Qt version combobox and click Apply button. From now you should be able to create, build and run empty Qt project.
Though OP is asking about Windows, this error also occurs on Ubuntu Linux and Google lists this result first when you search for the error»QtCreator: No valid kits found».
On Ubuntu this is solved by running:
This question is answered here and here, though those entries are less SEO-friendly.
No valid Kits found The problem occurs because qt-creator don’t know the versions of your qt, your compiler or your debugger. First off, let’s solve the Qt versions. It may normally solve the others too ;).
You try to create a new project, run select a kit and then there is no kit available in the list.

Руководство по сборке Qt со статической компоновкой под Windows
- Visual Studio 2017 или 2019
- Исходники Qt
Открываем x64 Native Tools Command Prompt
Создаем папку для сборки
Запускаем конфигурационный скрипт
- skip <module> — исключает из процесса сборки отдельный подмодуль
- nomake examples — исключает из процесса сборки примеры программ
- nomake tests — исключает из процесса сборки тесты
- platform <platform> — определяет платформу, для которой будет собран Qt, в данном случае Windows с MSVC
- no-opengl — не использовать OpenGL для отрисовки интерфейса
- qt-zlib , qt-libpng , qt-libjpeg — использовать библиотеки zlib , libpng , libjpeg поставляемые вместе с Qt
- opensource — использовать open source вариант Qt
- confirm-license — автоматически принять лицензию Qt
- debug-and-release , release , debug — варианты сборок
- static , static-runtime — включить статическую компоновку Qt и runtime
- prefix <prefix> — путь до папки, в которую будут скопированы откомпилированные файлы Qt
Запускаем сборку Qt (займет достаточно много времени)
Открываем «Параметры», выбираем «Комплекты» и переходим на вкладку «Профили Qt»
Нажимаем кнопку «Добавить…» и указываем путь до qmake.exe
Вводим название для нового профиля и нажимаем кнопку «Применить»
Переходим на вкладку «Комплекты». Копируем комплект с соответствующим компилятором (в данном случае MSVC)
В свойствах нового комплекта выбираем новое название, а также выбираем только что добавленный нами профиль Qt. Нажимаем «ОК»
Подключение комплекта к существующему проекту
Открываем проект в QtCreator. Переключаемся в режим «Проекты»
В списке профилей выбираем новый профиль Qt
Для сборки с нужным комплектом слева внизу выбираем наш профиль Qt и запускаем сборку
Adding Kits
Qt Creator groups settings used for building and running projects as kits to make cross-platform and cross-configuration development easier. Each kit consists of a set of values that define one environment, such as a device, compiler, Qt version, and debugger command to use, and some metadata, such as an icon and a name for the kit. Once you have defined kits, you can select them to build and run projects.
Qt Creator supports development for the desktop and for the following types of devices:
Filtering Kit Settings
Typically, only a subset of the kit settings is relevant for a particular setup. Therefore, Qt Creator plugins register sets of relevant settings that you can view and modify in Edit > Preferences > Kits. For example, if you use CMake to build all your projects, you can hide Qbs and qmake settings by default.
To hide and show settings in the Kits tab for the current kit, select Settings Filter. To view and modify the settings displayed when you add a new kit, select Default Settings Filter.
Specifying Kit Settings
-
Select Edit > Preferences > Kits > Add.
To clone the selected kit, select Clone.
Qt Creator uses the default kit if it does not have enough information to choose the kit to use. To set the selected kit as the default kit, select Make Default.
Kit Settings
The following table summarizes the available kit settings.
| Setting | Value |
|---|---|
| Name | Name of the kit. You can use variables to generate the kit name based on the values you set in the other fields. |
| Image to use as an icon for the kit. | |
| File system name | Name for the kit to use as a part of directory names. This value is used for the CurrentKit:FileSystemName variable, which determines the name of the shadow build directory, for example. |
| Device type | Type of the device. |
Double-click the icon next to the field to select the image that is displayed in the kit selector for this kit. You can use any image in a supported file format (for example, PNG). The image is scaled to the size 64×64 pixels. For example, using the compiler logo as an icon allows you to easily see, which compiler is used to build the project for the selected kit.
This setting is used to tell the code model which compiler is used. If your project type and build tool support it, Qt Creator also tells the build tool to use this compiler for building the project.
For Android kits, the Android GDB server field will display the path to GDB server executable.
Qt Creator checks the directories listed in the PATH environment variable for the qmake executable. It refers to the qmake executable it finds as Qt in PATH and selects it as the Qt version to use for the Desktop kit that is created by default.
Editing Qbs Profiles
To view the Qbs profile associated with the kit, select Edit > Preferences > Qbs > Profiles.
You can add keys and values to the profile or remove them from it, as well as modify existing values. For a list of available keys and values, see List of Modules in the Qbs Manual.
To edit the Qbs profile associated with the kit:
-
In Edit > Preferences > Kits, select the kit, and then select Change next to the Additional Qbs Profile Settings field to open the Custom Properties dialog.
To modify an existing value, double-click it in the Value field.
To remove the selected property, select Remove.
