I have a file in LaTeX format. The problem is the file does not accept any changes in the text and gives the same PDF file. I have used Winedit to compile it but the same problem occurs. Please see if you can overcome this technical issue.

The log file say:

Errors were reported during the execution of PDFTeXify.
*** WinEdt captured the following error file:

  • Welcome to TeX SX! Perhaps another main file is defined in WinEdt, and it launches the compiler on this other file? What does the log file say? – Bernard Sep 6 '15 at 16:12
  • Another possibility: WinEdt launches the compiler on another copy of your file and, this copy not being modified, the resulting .pdf isn't modified either. – Bernard Sep 6 '15 at 16:15
  • @Bernard: I add the message of the log file in the question. – zeraoulia Sep 6 '15 at 16:46

    @zeraoulia: the first thing to is updating MiKTeX: you use version 2.7 (end-of-life: 2/17/2007!). LaTeX has changed a lot since then, and it would be a loss of time to try make it work. You should download the basic installer, and update or download packages you need that aren't in the basic installation progressively. Keep the old version for some time until you're sure version 2.9 works fine. – Bernard Sep 6 '15 at 17:54
  • Something is very seriously wrong. It is hard to know what exactly. Is the file you are trying to compile supposed to produce a document? Because pdfTeX is not running in a mode which might do that. It seems to be running in the mode it uses to generate format files (.fmt) which are then used when compiling documents. At least, that is how it looks. Since you should certainly update anyway, that is surely the best option. – cfr Sep 6 '15 at 20:23
