任何人都可以建议我任何解决方案.我也有一些解决方案,说我改变Word dlls的访问权限使用DCOMCNFG但仍然得到相同的错误.但在一段时间它工作正常...所以我认为代码不是问题.还how I will find which account is using my current application.(例如网络服务,管理员等)

Answer 1

我找到了解决方案,

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选项并选择选项卡安全性.您将获得启动和激活权限选项 - >选择自定义然后单击编辑并添加将以完全访问权限运行您的应用程序的用户.

这就是全部,这解决了我的问题,这将有所帮助.
