        try:
            from universal_os_fixes import UniversalOSFixes
            universal_fixes = UniversalOSFixes()
            if universal_fixes.run_comprehensive_setup():
                return True
        except ImportError:
            pass
        
        # Fallback to legacy fixes
        # ... existing code ...

🧪 Testing Procedures

1. Pre-Installation Testing
