How To Fix The Lumion Error – Channel Not Found?

Are you facing a Lumion error – Channel not found in installation skipping load routine at the startup of your Lumion program? Scroll below and help yourself.

This error is also popular as the “Lumion channel not found”. Some of my YouTube subscribers from the Mad About Construction channel dropped me a message via WhatsApp that they were facing an error;

1. “StringOperator.dll” error followed by “Channel not found in installation skipping load routine” then it shows the code through message window like “F26BB4OB-B196-4AB9-B59E-FA7C8FF436F9” and then it shows the path “In Group: C:\Program Files\Lumion 11.0\ArchitectEdition\OO Loader.cgr” – Click here for the solution of such error.

Note: – In this error, the .dll file name could be different for all the users. So, if you see the different .dll file name instead of StringOperator.dll, the solution for that error can still be the same as shown below. For example, System_Command.dll, Win32_SetWindowText.dll, XMLDOMObject.dll, ZipCompression.dll, PanoCommand.dll etc.

What is the reason for the error “Channel not found in installation skipping load routine”?

When you open Lumion, you can face the error message “StringOperator.dll” error. If you click on ok, it will give another message “Channel not found in installation skipping load routine”. If you click on ok, it shows the code through a message window like “F26BB4OB-B196-4AB9-B59E-FA7C8FF436F9”, and again, if you click on ok, then it will show the path “In Group: C:\Program Files\Lumion 11.0\ArchitectEdition\OO Loader.cgr”.

Cause of error:

Your computer’s protections like windows security, windows defender or 3rd party antivirus can cause this error. When you run the Lumion program, your windows defender or antivirus identifies some files as a threat to your computer and add that file to the quarantined list.

Once your computer protection adds it to the quarantined list, it does not allow your computer to access that file. In this case, we can fix this problem by below one of two methods;
