在为 VS 2017 安装 Oracle 开发工具时，我遇到了这个错误消息，到目前为止我还没有解决它。
Error Message pointing me to a log file
错误消息将我指向一个日志文件，其中找到了以下堆栈跟踪：

据我了解，它的要点是在尝试安装 Visual Studio 扩展时正在运行另一个安装。在此过程中我当然没有自己安装一些东西，但是我还检查了任务管理器是否有 ein msiexec 进程正在运行。有时有一个正在运行，但我在没有 msiexec 进程运行时收到相同的错误消息。
我可以想象运行两个安装程序的唯一方法是 Oracle 开发工具安装程序启动 Visual Studio 扩展安装程序。然后有两个安装程序正在运行。但是我不太相信这个结论，因为这应该在其他地方发生过，但我没有在任何地方找到我的错误消息。
我尝试过的事情：
- 多次重新安装并重新启动并以管理员身份运行。
- 我尝试在错误发生后手动安装扩展程序，成功结束，但是当我尝试在 Visual Studio 中使用自定义工具时，我收到一条错误消息。
Visual Studio 2017 版本：15.9.18
