⚠️ A Serious Word of Caution (Read this before downloading)

• It is 17 years old. This software was not designed for Windows 10 or Windows 11. Running it on a modern OS may cause system instability or boot loops.
• Security Vulnerabilities: The code is ancient. Antivirus programs will likely flag it as a "HackTool" or "Riskware" because portable utilities from that era used packing methods that modern malware also uses.
• No Updates: The server that checked for license keys is long dead. You will likely need a crack or keygen to use the "Pro" features, which is a fast track to infecting your PC.
