Question

这是我在Intel i3笔记本电脑上全新安装的Windows 10（64位）上的Visual Studio 2019 Community Edition的全新安装。

每当我尝试安装扩展名（例如CodeMaid）时，都会出现未找到COM ClassID的错误。我不确定为什么会出现此错误。从谷歌搜索和参考一些文章后，我认为此错误是由于64位计算机上的32位COM。 Visual Studio尝试在64位注册表下查找COM CLASSID，但由于它可能在32位注册表下而失败。这只是一个疯狂的猜测。

只需添加一下，“帮助”下的“报告问题”对我也不起作用，但是NuGet软件包管理器运行良好；我可以下载和引用NuGet软件包。不确定是否与扩展相关，但是只是将这些信息发布给您。

请帮助我解决此错误。

我正在复制尝试安装CodeMaid扩展程序时遇到的错误的完整错误日志。这肯定不是特定于扩展程序的错误，因为当我尝试更新“ Live Share”之类的扩展程序时，我遇到了相同的错误。

有关详细信息，请查看以下错误日志：

Answer 1

实际上，当您卸载VS时，可以对PC上的VS进行彻底的清除，然后重新安装。

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。

如果无法卸载VS2019，则可以尝试此操作。

旁边，

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

完成后，请确保没有当前VS2019版本的文件夹（社区 * 专业 ** 企业 *）在C:\Program Files (x86)\Microsoft Visual Studio\2019下。

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

然后，右键单击vs_installer->单击以管理员身份运行，然后安装相关的扩展开发工作负载，如下所示：

最后，当您完成安装后，请再次进行测试。
