QDirStat is primarily designed for Linux and other Unix-like desktop environments. The downloadable archive on this site is source code and should not be mistaken for a native Windows installer.
A technically advanced Windows user may experiment with a Linux environment, graphical forwarding or a container-based remote interface. Those paths introduce extra setup, storage mapping and permission considerations.
Why there is no simple Windows installation
Different desktop stack
QDirStat relies on a Qt and Unix-like build environment. Although Qt is cross-platform, the complete project workflow is not presented here as a supported native Windows package.
Source ZIP is not an EXE
Extracting the archive does not install an application. It provides code that must be built using a suitable toolchain and project instructions.
Possible advanced approaches
Linux virtual machine
A virtual machine offers a complete Linux desktop but sees Windows files only through shared folders or mounted storage.
Remote or container interface
A container can display QDirStat through a browser layer, but file paths and permissions must be mapped carefully.
Unix-like subsystem
A subsystem may run Linux applications, yet graphical integration and access to Windows storage vary by system configuration.
Choose a Windows-native workflow when possible
Reduce setup overhead
A native utility is generally easier to install, update and integrate with Windows drives.
Avoid path confusion
Native applications show Windows paths directly, while virtual or container layers can translate them into different mount locations.
Do not force the wrong package
Verify file type
A ZIP containing source folders is not a failed installer.
Match software to the platform
Use QDirStat where its Linux-focused workflow is a good fit rather than treating compatibility experiments as the default path.
