I am using Windows 7, newest patch.
I used Installer to install Forge. That was installer forge-1.8-11.14.3.1450-installer-win.exe. Afterwards, I used jar version of that installer, still did the same.
It made folder for that release in %appdata%/.minecraft/versions, but it put only .json file there, not .jar. Only thing I can give is what was on my launcher development console:
