Many of the files referenced weren't installed from the downloaded ZIP file. For example, there is no
C:\Users[USER]\Desktop\Lexos\lexos\frontend\node_modules\

The install doesn't seem to be accurate anymore. Or at least, the zip doesn't contain files and folders referenced in the above code

Compare the downloaded ZIP with the paths requested while running python run.py, especially lexos/frontend/node_modules/ and the missing jQuery and Intro.js files. Check how the package is assembled and verify the Windows installation can serve every referenced asset without the reported errors.
