The "Channel not found in installation" error in Lumion typically occurs when your antivirus software (most often Windows Defender) has quarantined or deleted essential .dll files from the Lumion installation directory. This causes the software to skip its normal load routine because it cannot find the required "channels" for core functions. Top Fix: Restore Quarantined Files
The most direct way to resolve this is to recover the missing files from your security history.
Close Lumion: Ensure any stuck Lumion processes are closed via Task Manager. Check Protection History: Open Windows Security > Virus & threat protection.
Click on Protection history and filter for "Quarantined items".

Administrator Privileges: Right-click the Lumion shortcut and select Run as administrator to ensure it has the permissions needed to load its internal "channels".
Missing System Software: Repair your Microsoft Visual C++ Redistributables. Locate the Redist folder inside your Lumion installation directory and run VC_redist.x64.exe as an administrator. Impact on Usage:
DLL Conflict (Older Versions): For Lumion 10.0–10.3.2, a Windows update sometimes creates a conflict with onnxruntime.dll. Try moving this file from the \3rd\ subfolder directly into the main Lumion installation folder (where Lumion.exe is located).
