任何人都可以向我建议任何解决方案。因为我也有一些解决方案说我使用 DCOMCNFG 更改 Word dll 的访问权限，但仍然遇到相同的错误。但在一些它正常工作的时间......所以我认为代码不是问题。 还有 我如何找到哪个帐户正在使用我当前的应用程序。(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 选项并选择安全选项卡。在这里您将获得启动和激活权限选项 ->选择自定义并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。

就是这样，这解决了我的问题希望这会有所帮助。
