按Win+R，输入%temp%，然后删除所有文件，并重新启动Visual studio。

勾选“为所有项目执行此操作”，如果需要按跳过按钮。

在我的情况下，我使用的是2019版。

我想装置是在后台进行的。过一会儿门就开了。如果通过查看安装程序有一个丢失的包，您也可以尝试安装它。

在我的情况下，我打开Visual Studio安装程序，看到它说

设置失败。单击“重试”继续。

我重新安装后，问题就消失了。

很可能Visual Studio正在更新，就像错误消息暗示的那样，如果你等待几分钟更新完成，你应该能够再次运行Visual Studio而没有问题。

If the problem persists or if you're just curious, open up your task manager and see if there is anything related to (Microsoft) Visual Studio running but don't just kill the process. Check instead if the process is using any resources - if it has a high I/O count, then it's actually updating and you should let it do its thing. If CPU-usage and memory usage remain mostly constant and there is no disk activity for the process for several minutes, this could mean that the process is stuck. You might have to kill it, but proceed with caution. Hopefully if this is an update for Visual Studio, the process name should include a version number or some sort of indication of what kind of update is being applied that you can use to search for more information through a search engine or through Microsoft's online resources.

进入任务管理器。进程下查找vn。单击“结束进程”。

在这里输入图像描述 打开任务管理器，有一个名为VSStandardCollectorService150的服务，右键单击启动它。 这是为我在VS2019上的同一问题工作。
