Preparation & Cleanup:

1. Uninstall any older or conflicting FL Studio builds.
2. Clean up residual registry entries if necessary:
   HKEY_CURRENT_USER\Software\Image-Line\Registrations

Installation Steps:

1. Run the official retail setup installer (flstudio_win64_26.1.6.5639.exe) as Administrator.

  • Copy the provided dsound.dll file directly into your FL Studio installation root directory:
    C:\Program Files\Image-Line\FL Studio 2026\
    (Note: This DLL hook blocks WinInet calls. Alternatively, configure your Windows Firewall to block all outbound connections for FL64.exe).
