I ran a Google search but nothing too clear showed up. I'm looking for a Windows 7 compatible version of pdflatex.exe to help me in typesetting some math I have in an Illustrator project.

I heard about it through this tutorial: http://www.justskins.com/forums/math-equation-editing-in-86877.html

• Are you sure they are talking about `pdflatex.exe` and not about MathType? – Gonzalo Medina Mar 27 '12 at 0:12

`pdflatex.exe` is part of a whole suite of software called a TeX Distribution. You can't just download the executable. There are two main distributions available for Windows: TeX Live and MikTeX. Both are very good. Whether or not installing them and learning enough LaTeX to solve your problem is a worthwhile effort may well depend on how often you are likely to do what you're doing.

See the following question on the differences between the two distributions.

What are the advantages of TeX Live over MiKTeX?

If this is a one off type situation, you may also want to take a look at some of the online LaTeX compilers:

• If you're a beginner, proTeXt, which includes MiKTeX, might also be a good idea; see tex.stackexchange.com/a/26021/4012. – doncherry Mar 27 '12 at 8:07
• Well, you can download it. Whether there is any point doing so is, of course, a different matter. – cfr Mar 12 '16 at 23:18

I can not get the motivation behind asking only for `pdflatex`. Nevertheless, (for windows) you can download 'MiKTeX' basic installer and install. You can find `pdflatex` in the folder `C:\Program Files\MiKTeX 2.9\miktex\bin`.

If your intention is for writing some equations, you can try `Mathtype`. It has compatibility with many applications including Adobe Illustrator and InDesign.

W32TeX offers this. It can be found at a mirror under pdftex-w32.

To get it to compile TeX you will also need the web2c-w32 and web2c-lib packages. If you want to compile LaTeX, add latex package as well.
