l2gen will not auto-populate an L2 file when I input a L1 files from Landsat 8 Collection 2

The images I have obtained are from EarthExplorer Landsat8 Collection 2 Level 1. When I input the MTL.txt file, the output file does not auto population as NASA webinar tutorials have said it should.

Please let us know what version of SeaDAS and what tag of Science Processors (OCSSW) you are using? Or you can do SeaDAS-Toolbox -> Software & System Info and post the result here.

Please also copy and paste the Landsat 8 L1 filename here, for it's hard to read the file name on the screenshot you shared.

It seems you don't have Science Processors (OCSSW) installed.
For l2gen to work correctly on Landsat 8 collection 2 L1 files, you probably need to use Science Processors (OCSSW) V2023.2 and SeaDAS 8.3.0.

You can download SeaDAS 8.3.0 here and follow the instruction "Install With GUI" to install the Science Processors, including olil8 and olil9 https://seadas.gsfc.nasa.gov/downloads/

Here is the help page for install_ocssw - https://seadas.gsfc.nasa.gov/help-8.3.0/processors/InstallOCSSW.html
