 When the Windows agent starts, `C:\OGP64\agent_start.bat` should be launched from the Cygwin root itself. It verifies the `gameserver` account, normalizes text files, validates `OGP\ogp_agent.pl`, and then launches the agent in the same console window. It should not call an installer wrapper from the start script.
