What I have tried:

<pre>  StreamWriter sw = new StreamWriter(@"D:\localmachineProducts64.txt", true);
            using (RegistryKey rk = Registry.LocalMachine.OpenSubKey(uninstallKey))
            {
                foreach (string skName in rk.GetSubKeyNames())
                {
                    using (RegistryKey sk = rk.OpenSubKey(skName))
                    {
                        try
                        {
                            sw.Write(sk.GetValue("DisplayName") + "\t" + sk.GetValue("InstallLocation"));
                            sw.Write(sw.NewLine);
                            count++;
                        }
                        catch (Exception ex)
                        {
                            MessageBox.Show(ex.Message);
                        }
                    }
                }
                sw.Write("Total count  :=" + count);
            }
            sw.Close();

推荐答案

你犯的是最严重的错误。您确定所需的值是否在卸载密钥下的每个密钥中。它不是。



无法获得列出的每个应用程序的安装位置。



此外，不是安装的每个应用程序甚至都显示在卸载密钥下！

You're making the most egregious of mistakes. Your ASSUMING that the value you want is in every one of the keys under the Uninstall key. It's not.

It's impossible to get the installed location of every application listed.

Also, not every application that's installed even shows up under the Uninstall key!
