GameLoop Installation Stuck or Failed — Fix for Windows PC

GameLoop failing to install — or hanging at a percentage and never progressing — happens most often on Windows 10 and 11 due to antivirus interference, insufficient disk space, conflicting previous installations, or a corrupted installer download. **Why installation fails:** GameLoop installs a system-level driver for its virtualization engine and modifies Windows network adapters for game routing. Security software frequently blocks these components, treating them as suspicious behavior from an unknown installer. **Common symptoms before reading the fixes:** | Symptom | Likely cause | |---------|--------------| | Installer stuck at 0% or never starts | Antivirus or permissions block | | Progress bar freezes at 30–90% | Disk space or write permissions | | Error code 1603 or 1305 | .NET/VC++ runtime missing | | "Installation failed" with no error detail | Previous installation conflict | | Installer downloads but won't run | SmartScreen / antivirus quarantine |
