Hi-- I've been using LyX for many years and know how to change previewers, but no matter what I do now, documents come up in Yap. I'm running LyX 2.0.7 on Windows 7. What I've done:
1. Installed SumatraPDF 2. Added ;C:\Program Files (x86)\SumatraPDF to the "PATH prefix" item in Tools > Preferences > Paths 3. Gone to Tools > Preferences > File Handling > File Formats and (a) set PDF(LuaTeX) as the default output format; (b) set the viewer for that format (and also for pdflatex) to SumatraPDF.exe 4. Reconfigured I have also tried changing the name of the Yap executable, but then LyX just shows a "successfully previewed" message in the status bar without showing me the output at all. I've been working around this by exporting LuaTeX, but it would be great to have my previewer back. Please help. Thanks, Steve
