Component Names for Installation
Quick Installation with Alias Packages
Note: Quick installation with alias packages will be available in Qt Online Installer release 4.8.
Instead of searching for specific package names for installation, you can use alias packages to install the most common configurations. Alias packages are a shortcut to include the actual packages for an easier installation experience.
To list the existing alias packages, use the following command on the command line interface:
installer.exe / maintenancetool.exe search
The contents of the alias packages are listed in the table below.
Note: Qt 6.8.0 release is used in the alias package examples listed below. Always remember to use the packages that match the Qt release you are working on.
| Alias package name | Qt Online Installer (package content) |
|---|---|
| qt6.8.0-essentials |
|
| qt6.8.0-essentials-dev |
|
| qt6.8.0-full |
|
| qt6.8.0-full-dev |
|
| qt6.8.0-full-dbg |
|
| qt6.8.0-sdk |
|

Listing Non-Alias Packages
To list the non-alias packages, use the following command on the command line interface:
installer.exe / maintenancetool.exe search --type package
Advanced Searching for Specific Installation Packages
Search available packages with the search command and regular expressions: search <regexp>. You can filter the results with --filter-packages <regexp>. For example, filtering with the display name information can help search.
For example, the following command finds all MSVC 2019 packages for Qt 6.8.0:
search .*680.*msvc2019
You get the same result when you filter the search result as follows:
search --filter-packages DisplayName=MSVC 2019,Version=6.8.0
As a result, you get the following packages:
<availablepackages>
<package name="qt.qt6.680.win64_msvc2019_64" displayname="MSVC 2019 64-bit" version="6.8.0-0-202303290841"/>
<package name="qt.qt6.680.win64_msvc2019_arm64" displayname="MSVC 2019 ARM64 (TP)" version="6.8.0-0-202303290841"/>
</availablepackages>
You can also use filtering when you search all Qt versions that some package is provided for. For example, search all Qt Charts packages provided for Qt versions:
search --filter-packages DisplayName=charts
The search result is as follows:
<availablepackages>
<package name="qt.qt5.5125.qtcharts" displayname="Qt Charts" version="5.12.5-0-201909090651"/>
<package name="qt.qt6.641.addons.qtcharts" displayname="Qt Charts" version="6.4.1-0-202211101525"/>
<package name="qt.qt5.5123.qtcharts" displayname="Qt Charts" version="5.12.3-0-201904161619"/>
Installing Without User Interaction
By default, Qt Online Installer or Qt Maintenance Tool may ask for additional information during installation, which requires user attention. Unattended usage via the command line interface is possible by providing all the requested information beforehand with appropriate options.
New Installation with Qt Online Installer
You can do new installations from the command line interface without user interaction as follows:
- Define the Qt Online Installer executable.
- Define the installation directory with
--root. - Use the
install <list of packages>command with options for unattended usage. See the full list of options in Options for Unattended Usage.
The following examples demonstrate how you install Qt 6.8.0 binaries with Qt Online Installer for Windows, macOS, and Linux. The unattended commands automatically accept the licenses (--accept-licenses), answer all message queries with their default answer (--default-answer), and skip asking for permission to continue performing (--confirm-command):
# Windows: new installation with Qt Online Installer qt-unified-windows-x64-[Qt Online Installer version]-online.exe --root C:\Users\[username]\installation_dir --accept-licenses --default-answer --confirm-command install qt.qt6.680.win64_msvc2019_64 # macOS: new installation with Qt Online Installer qt-unified-macOS-x64-[Qt Online Installer version]-online.dmg --root /home/<username>/installation_dir --accept-licenses --default-answer --confirm-command install qt.qt6.680.clang_644 # linux: new installation with Qt Online Installer qt-unified-linux-x64-[Qt Online Installer version]-online.run --root /home/<username>/installation_dir --accept-licenses --default-answer --confirm-command install qt.qt6.680.gcc_64
Options for Unattended Usage lists all available options for unattended usage.
Updating Installation with Qt Maintenance Tool
You can update existing installation from the command line interface without user interaction as follows:
- Define the Qt Maintenance Tool executable.
- Use
install <list of packages>with options for unattended usage. See the full list of options in Options for Unattended Usage.
The following examples demonstrate how you add Qt 6.8.0 binaries with Qt Maintenance Tool to an exsting installation on Windows, macOS, and Linux. The unattended commands automatically accept the licenses (--accept-licenses), answer all message queries with their default answer (--default-answer), and skip asking for permission to continue performing (--confirm-command):
# Windows: update installation with Qt Maintenance Tool MaintenanceTool.exe --accept-licenses --default-answer --confirm-command install qt.qt6.680.win64_msvc2019_64 # macOS: update installation with Qt Maintenance Tool MaintenanceTool.app/Contents/MacOS/MaintenanceTool --accept-licenses --default-answer --confirm-command install qt.qt6.680.clang_64 # linux: update installation with Qt Maintenance Tool MaintenanceTool.run --accept-licenses --default-answer --confirm-command install qt.qt6.680.gcc_64
Options for Unattended Usage
The following table lists all options for unattended command line usage:
| Option for unattended usage | Description |
|---|---|
--accept-licenses | Automatically accepts all license agreements. |
--accept-obligations | In the opensource installations, accepts Qt Open Source usage obligations without user input. |
--default-answer | Answers all message queries with their default answer. |
--auto-answer <identifier=value> | In case you want different answers to certain queries, you can use this option. For example, --auto-answer telemetry-question=Yes,AssociateCommonFiletypes=Yes. See all message identifiers in Message Identifiers for --auto-answer. |
--accept-messages | Accepts all message queries. |
--reject-messages | Rejects all message queries. |
--confirm-command | By default, Qt Online Installer and Qt Maintenance Tool print a summary of components to be affected by the option. Then they ask for permission to continue acting, to prevent accidental changes. This option skips asking for permission to continue. |
--email <your_email> | Provides the email when you log in from the command line. For more information, see Providing Login Information. |
--pw <your_pw> | Provides the password when you log in from the command line. For more information, see Providing Login Information. |
--file-query <identifier=value> | Sometimes Qt Online Installer asks for a file or a folder location. You can provide the location with --file-query <identifier=value>. For example, --file-query PathForSDP7=<path_to_sdp>.The identifiers are printed into the command line before the actual question and message type. You can pick up the identifiers from there. |
Message Identifiers for --auto-answer
Use the --auto-answer option to provide answers to certain queries. The following table lists known identifiers and values used for --auto-answer:
| ID | Values | Default |
|---|---|---|
| OperationDoesNotExistError | Abort, Ignore | Ignore |

| stopProcessesForUpdates | Retry, Ignore, Cancel | Cancel |
| installationErrorWithCancel | Retry, Ignore, Cancel | Cancel |
| installationErrorWithIgnore | Retry, Ignore | Ignore |
| AssociateCommonFiletypes | Yes, No | Yes |
| telemetry-question | Yes, No | Yes |
Providing Login Information
Qt Online Installer and Qt Maintenance Tool have a forced login. The forced login uses information on the qtaccount.ini file if it is available in cache. You find qtaccount.ini as follows:
| Host | qtaccount.ini location |
|---|---|
| Windows | C:\Users\<username>\AppData\Roaming\Qt |
| macOS | /Users/<username>/Library/Application Support/Qt/qtaccount.ini |
| Linux | /home/<username>/.local/share/Qt/qtaccount.ini |
Optionally, you can login either from the command line using the switches for email and password: --email <your_email> and --pw <your_pw>.
Alternatively, you can save the jwt token to the environment variable QT_INSTALLER_JWT_TOKEN. You find the token in the qtaccount.ini file.
Installing With User Interaction
You can use the command line interface with user interaction as follows:
- Define the executable:
- Qt Online Installer if you need to do a new installation.
- Qt Maintenance Tool if you need to update an existing installation.
- When you do a new installation, define the installation directory with
--root - Use
install <list of packages>to install the listed packages.
The following examples demonstrate how you create a new installation of Qt 6.8.0 binaries with Qt Online Installer for Windows, macOS, and Linux:
# Windows: new installation with user interaction qt-unified-windows-x64-[Qt Online Installer version]-online.exe --root C:\Users\[username]\installation_dir install qt.qt6.680.win64_msvc2019_64 # macOS: new installation with user interaction qt-unified-macOS-x64-[Qt Online Installer version]-online.dmg --root /home/<username>/installation_dir install qt.qt6.680.clang_64 # linux: new installation with user interaction qt-unified-linux-x64-[Qt Online Installer version]-online.run --root /home/<username>/installation_dir install qt.qt6.680.gcc_64
The following examples demonstrate how you update your existing installation by installing the Qt 6.8.0 binaries with Qt Maintenance Tool:
# Windows: update installation with Qt Maintenance Tool MaintenanceTool.exe install qt.qt6.680.win64_msvc2019_64 # macOS: update installation with Qt Maintenance Tool MaintenanceTool.dmg install qt.qt6.680.clang_64 # Linux: update installation with Qt Maintenance Tool MaintenanceTool.run install qt.qt6.680.gcc_64
Uninstalling Packages
The command line interface provides two commands for uninstalling packages:
- The
remove <list of packages>command uninstalls the listed packages. - The
purgecommand uninstalls all installed packages.
You should use both commands with Qt Maintenance Tool.
By default, Qt Maintenance Tool prints a summary of components to be affected by the command. Then the tool asks for permission to continue acting, to prevent accidental changes. Use --confirm-command to skip asking for permission to continue.
The following example uninstalls the Qt 6.8.0 binaries without user interaction:
# windows MaintenanceTool.exe --confirm-command remove qt.qt6.680.win64_msvc2019_64 # macOS MaintenanceTool.dmg --confirm-command remove install qt.qt6.680.clang_64 # linux MaintenanceTool.run --confirm-command remove qt.qt6.680.gcc_64
The following examples uninstall all packages and ask for permission to continue performing the action:
# Windows MaintenanceTool.exe purge # macOS MaintenanceTool.dmg purge # Linux MaintenanceTool.run purge
Listing Installed Packages
The list command lists all packages you have installed. Use the command with Qt Maintenance Tool as follows:
# Windows MaintenanceTool.exe list # macOS MaintenanceTool.dmg list # Linux MaintenanceTool.run list
Checking Updates
The check-updates command checks the updates that are available for the installed packages. Use the command with Qt Maintenance Tool as follows:
# Windows MaintenanceTool.exe check-updates # macOS MaintenanceTool.dmg check-updates # Linux MaintenanceTool.run check-updates
Updating Packages
The update command updates the installed packages. Use the command with Qt Maintenance Tool as follows:

Selecting Mirror for Opensource
Qt Online Installer has an option for selecting a mirror for opensource metadata and downloads. Set the mirror from the command line with the --mirror option.
For example, use --mirror as follows:
installer(.exe) --mirror http://www.nic.funet.fi/pub/mirrors/download.qt-project.org installer(.exe) --mirror http://ftp2.nluug.nl/languages/qt maintenancetool(.exe) --mirror http://qt.mirror.constant.com
As the example shows, don't use the full path but use the path before '/online' (no forward slash at the end).
You find the available mirrors from https://download.qt.io/online/qtsdkrepository/windows_x86/root/qt/Updates.xml.mirrorlist.
