I found the solution,
我找到了解决方案，
using DCOMCNFG.exe open it and go to Component Service ->Computers->My Computer->DCOM Config-> check for Microsoft Office Word option and select tab Security.Here you will get the options for Launch and Activation Permission->select Customize and click on edit and the add the user that will runs your Application with full access.
使用 DCOMCNFG.exe 打开它并转到组件服务 -> 计算机 -> 我的电脑 -> DCOM 配置 -> 检查 Microsoft Office Word 选项并选择选项卡 Security.Here 您将获得启动和激活权限的选项 -> 选择自定义并单击编辑并添加将运行具有完全访问权限的应用程序的用户。

One thing I did on my server was to open Microsoft Word on the machine and this seemed to cause the error to go away.
我在服务器上做的一件事是在机器上打开 Microsoft Word，这似乎导致错误消失。

you can create another user , then login with that and create remote to 121.0.0.1 and main user (loopback to rpc!!!) then diconnect from new user and you will have interactive user
您可以创建另一个用户，然后使用该用户登录并创建远程到 121.0.0.1 和主用户（回送至 rpc ！！！）然后从新用户断开连接，您将拥有交互式用户
