Dear List, I have Windows 10, and WinEdt 10.3., actual verison. I wanted to do the test, but only I got this, after compiling: Command Line: C:\texlive\2021\bin\win32\context.exe --synctex=-1 "context-test.tex" Startup Folder: C:\Users\Hermann\Downloads\cont-tmf\tex\context\test\mkiv mtxrun | unknown script 'context.lua' or 'mtx-context.lua' _____________________________________________________________________ ConTeXt Compilation Report (Pages: 0) Errors: 0 Warnings: 0 Bad Boxes: 0 What is wrong here?
