python脚本，用于在注册表中的Uninstall文件夹中查找已安装的程序

Question

我正在创建一个python脚本来查找在注册表中的卸载文件夹中安装的程序，该脚本在32位计算机上运行得非常好，但在64位计算机上出现wmi错误。 无法获取64位上python的wmi模块机器。是有一个吗？ 请忽略缩进错误。 我在某论坛上发现了这个剧本，很抱歉没有给予相应的作者应有的信任

r = wmi.Registry()
result, names = r.EnumKey (hDefKey=HKEY_LOCAL_MACHINE, sSubKeyName=r"Software\Microsoft\Windows\CurrentVersion\Uninstall")

    separator = "*" * 80
    keyPath = r"Software\Microsoft\Windows\CurrentVersion\Uninstall"
    for subkey in names:
       try:

            path = keyPath + "\\" + subkey
            key = OpenKey(HKEY_LOCAL_MACHINE, path, 0, KEY_ALL_ACCESS)

            try:
                temp = QueryValueEx(key, 'DisplayName')
                temp1 = QueryValueEx(key, 'DisplayVersion')
                temp2 = QueryValueEx(key, 'Publisher')
                display = str(temp[0])
                display_ver=str(temp1[0])
                display_p=str(temp2[0])

                print ('Display Name: ' + display + '\nDisplay version:  ' + display_ver + '\nVendor/Publisher:  ' + display_p +'\nRegkey: ' + subkey + '\n')

            except:
                print ('Regkey: ' + subkey + '\n')


        except:
            fp = StringIO.StringIO()
            traceback.print_exc(file=fp)
            errorMessage = fp.getvalue()
            #error = 'Error for ' + key + '. Message follows:\n' + errorMessage
            #HelperFuncs.LogError(error)

这可能不是使用this实现的最好的代码，但它适用于我的应用程序。我希望你能用它或改进它。在

示例结果如下：

结果确保始终存在显示名称。考虑到我对Python还不熟悉，这个问题很难解决。但是不管怎样，如果某个应用程序在值列表中没有显示名称，它将使用最后一个键地址作为显示名称。在
