Research direction

Start by reproducing the configuration with Minecraft 1.4.7 and Forge 6.6.1.529, then inspect ForgeInstaller.downloadInstaller at ForgeInstaller.java:398 and the install-forge command path shown in the logs. Done means the image can locate and install this Forge version, or clearly reports that the old installer is unavailable.
