Lumion Channel Not Found In Installation Skipping Load Routine High Quality -
The error message "channel not found in installation skipping load routine high quality" typically indicates that Lumion cannot find or access specific core files required for startup or high-quality features. This often occurs because antivirus software has quarantined or blocked files in the "channels" folder, or due to a conflict with system-level libraries after a Windows update. Recommended Solutions
Add Antivirus Exclusions: This is the most common fix. Ensure your security software is not blocking Lumion's installation path.
Locate the Lumion installation folder (usually C:\Program Files\Lumion [Version]).
Add an exclusion for this entire folder in your antivirus settings (e.g., Windows Defender).
Check your antivirus Protection History to see if any .dll or channel files were recently blocked and select "Restore".
Move onnxruntime.dll (For Lumion 10 Users): If you updated Windows 10 (version 2004 or later), a conflict may exist between Lumion's and Windows' versions of this library. Close Lumion.
Navigate to the 3rd folder within your Lumion installation directory (e.g., C:\Program Files\Lumion 10.x\3rd).
Move the onnxruntime.dll file from that folder to the root Lumion folder (where Lumion.exe is located).
Run as Administrator: Right-click the Lumion shortcut and select "Run as administrator" to ensure the software has the necessary permissions to load all routines.
Repair Microsoft Visual C++ Redistributables: Missing or corrupted system files can prevent routines from loading.
Go to the Various\Redist folder in your Lumion installation directory.
Run VC_redist.x64.exe as an administrator and select Repair.
If these steps do not resolve the issue, you may need to reinstall Lumion with your antivirus temporarily disabled to ensure all "channels" are correctly placed. For official technical support, you can visit the Lumion Knowledge Base.
