Let me structure the response with sections: What is MCL Kannamai, Download Sources, Installation Steps, Common Fixes, Troubleshooting Tips, Alternatives, and Legal Notes. Make sure to keep the language clear and step-by-step for ease of use. Check if recent Windows updates include Tamil support by default, and note if users need to enable it through settings. Also, maybe clarify that the term "fixed" in the query refers to resolving display issues, not the font itself being fixed. Double-check any technical details to ensure accuracy.
