Visual 2019 (Community )-无法安装/更新扩展

Question

这是VisualStudio2019社区版的新安装，我在英特尔i3笔记本电脑上安装了新的Windows 10 (64位)。

每当我试图安装一个扩展(例如CodeMaid)时，我都会得到COM ClassID未找到的错误。我不知道为什么会有这个错误。从谷歌搜索，并参考了一些文章，我认为这个错误是由于32位COM上的64位机器。Visual试图在64位注册表下查找COM CLASSID，但由于它可能位于32位注册表下，所以失败了。这只是一个疯狂的猜测。

另外，“帮助”下的“报告问题”也不适用于我，但是NuGet软件包管理器运行良好；我可以下载和引用NuGet包。不确定这是否与扩展相关，但只需将此信息发布给您。

请帮助我解决这个错误。

当我试图安装CodeMaid扩展时，我正在复制完整的错误日志。这肯定不是一个特定于扩展的错误，因为当我试图更新像"Live“这样的扩展时，我会得到相同的错误。

有关详细信息，请查看以下错误日志：

Answer 1

实际上是，当您卸载VS时，您可以在您的PC上对VS进行深入的清理，然后重新安装它。

卸载时，请输入C:\Program Files (x86)\Microsoft Visual Studio\Installer\resources\app\layout\InstallCleanup.exe以运行该程序。它将卸载所有VS2017和VS2019版本的全部数据。

如果卸载VS2019不起作用，您可以尝试这样做。

除了，

删除C：\ 16.0_xxxx \xxx(当前用户)\AppData\Local\Microsoft\VisualStudio`‘下的文件夹。

完成它后，确保在version(community*professional**enterprise*)下没有当前VS2019的文件夹。

====================================

然后是，右键单击vs_installer->单击run管理员，然后安装相关的扩展开发工作负载，如下所示：

​

​

最后一个，当您完成安装后，请再次测试它。
