using(RegistryKey sqlServerKey = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\Microsoft SQL Server"))

    foreach (string subKeyName in sqlServerKey.GetSubKeyNames()) 
    { 
     if(subKeyName.StartsWith("MSSQL.")) 
     { 
      using(RegistryKey instanceKey = sqlServerKey.OpenSubKey(subKeyName)) 
      { 
       string instanceName = instanceKey.GetValue("").ToString(); 

       if (instanceName == "MSSQLSERVER")//say 
       { 
        string path = instanceKey.OpenSubKey(@"Setup").GetValue("SQLBinRoot").ToString(); 
        path = Path.Combine(path, "sqlserver.exe"); 
        return path; 
       } 
      }
