Forge doesn't launch

[Herowl]

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:

What should I do?

If there are needed any other logs, please tell me where to find them.

I am using SkaiaCraft, but still problem is with installer, as installer placed ONLY json file in version folder, not jar file.

The problem is not with the installer, it is with you using a cracked launcher instead of buying the game. Go buy the game and use the official minecraft launcher.

buy the game
