This is my first time using a LaTeX editor.
I installed the Windows version of Texmaker changing the C drive to D and leaving the rest of the install path the same.
Windows 7 Ultimate 64-bit
Texmaker 3.4.1 for Windows
I then did "A Local guide for using Texmaker" PDF
Basically create a simple Hello World document and save it.
When I went to process the file (Tools - PDFLaTeX) I received the Error: Log file not found!
I checked the configuration (Options -> configure Texmaker) and found no option for log files.
I checked for a log file under the D:\Program Files (x86)\Texmaker and found none.
I checked for a log path in the Windows registry using regedit and found none.
I checked the Texmaker issues and found Issue 97 but it does not help.
I then uninstalled and reinstalled Texmaker allowing it to use the default directory on the C drive. I still get the same error.
I installed MiKTeX as an administrator (didn't work as user) and chose the default options. After MiKTeX installed I was able to create a PDF file using Texmaker.
Also, correctly setting the PDF viewer options (Options -> Configure Texmaker -> Commands -> PDF Viewer) Built-in Viewer and Embed, I was able to preview the pdf in Texmaker (View -> PDF Viewer).
So, Texmaker is a LaTeX editor which generates a file containing LaTeX markup. MiKTeX is a program that converts the LaTeX markup into an output format such as PDF.
