This question already has an answer here:

Using WinEdt 10.2 on Windows, when I compiled a doc, automatically WinEdt opens the PDF with Acrobat Reader. And If I didn´t close that viewed file, I recompiled again and WinEdt closes the old PDF and show me the new one.

But I made any changes, or WinEdt copied the settings from my installed WinEdt 9,... and now... If I close the PDF, and then compile, WinEdt opens the just-compiled PDF with Acrobat Reader


If I didn´t close the old PDF, Winedt can´t open the new PDF with Acrobat Reader as weeks ago, and show me that message: enter image description here

How could I show the new PDFs without closing the old one just-compiled a minutes ago?

I usually use enter image description here

Excuse me for my little English.

  • Anyway, the recommended viewer is SumatraPDF: lightweight (12Mb vs 330 Mb), ultra fast, has a 64 bits version, and can perform direct and inverse search! – Bernard Nov 19 '17 at 21:00
  • @Bernard I think this is opinion based, isn't it? I'd recommend MuPDF as it doesn't come with any useless gui and just shows the PDF (though it is bigger than Sumatra), btw :) – Skillmon Nov 19 '17 at 21:04
  • @Skillmon: It's not entirely opinion-based; Acrobat Reader does lock the pdf when you recompile, whereas SumatraPDf does not. Incidentally, SumatraPDF is based on MuPDF. – Bernard Nov 19 '17 at 21:09
  • @Bernard but it is opinion based which of the non-locking viewers you use (just don't use Adobe's...) – Skillmon Nov 20 '17 at 12:46
