Ensure you have administrative privileges. Right‑click the installer and select “Run as administrator”. If the problem persists, check that your system meets the minimum requirements listed in the system requirements article.
The installer may be missing required libraries. Install the latest .NET runtime and Visual C++ Redistributable. After installation, retry the setup.
Disable any antivirus or security software temporarily. Some real‑time scanners interfere with file extraction. Once the installation completes, re‑enable your security tools.
Choose a different installation directory where your user account has write access, such as your C:\Users\%USERNAME%\AppData\Local\ folder. Alternatively, adjust folder permissions via right‑click → Properties → Security.
