Hi lyx manager.
Im a starter of Lyx and I have a problem. when I use an article, I got a following message: he selected document class (Article) requires external files that are not available. The document class can still be used, but the document cannot be compiled until the following prerequisites are installed: article.cls And I cannot reconfigure. Can you help me out? My texworks(Miktex) works properly. Your help would give me a big pleasure. Thank you. HeonJin
