# Why can't AucTeX see my TeXLive binaries? (Cygwin on Windows 7 x64)

I have installed the TeXLive distribution. From emacs running in cygwin mintty, the LaTeX binaries are visible from my `PATH` environment variable. I installed AucTeX using the built in Emacs package manager with the package from Elpa.

``````\$ which latex
/cygdrive/c/texlive/2016/bin/win32/latex
\$ which pdflatex
/cygdrive/c/texlive/2016/bin/win32/pdflatex
\$ latex
This is pdfTeX, Version 3.14159265-2.6-1.40.17 (TeX Live 2016/W32TeX) (preloaded format=latex)
restricted \write18 enabled.
**
``````

However, when I try `C-c C-c` from a LaTeX file, I get the following message:

``````TeX-command: ERROR: AUCTeX cannot find a working TeX distribution.
Make sure you have one and that TeX binaries are in PATH environment variable
``````

Is there some AucTeX variable I could customize to point it in the right direction to the TeX distribution? I am pretty confident my `PATH` is set correctly.
