If you have a lower-end PC that can't handle the 2.0 update, v1.61 is a great "classic" experience. However, if your hardware can handle it, you're better off looking for the v2.12 / Ultimate Edition to get the full, intended experience.

Given that this version is several years old, the swarm might be slower than the latest v2.12 releases. Check the seeder-to-leecher ratio before starting.

Be cautious with .zip files from unknown uploaders. Version 1.61 is an older build, so ensure you are sourcing this from a reputable site with a high seeder count to avoid malware or "fakes" that are just password-protected archives.
