Question

无论我尝试安装哪种VSIX，都会收到HRESULT E_FAIL错误。示例：当我打开VS2019时，被告知需要更新Data Lake Services和LIve Share VSIX。我单击以同时更新两者，并且当我关闭所有VS窗口时都会进行更新。关闭VS2019时，安装开始，并且立即收到此错误。另外，如果我尝试安装任何新的VSIX，也会收到相同的错误。
我的VS2019已完全更新，我是管理员，可以正常连接。

如果由于计算机空间不足而在外部硬盘中或安装Visual Studio的某个位置设置了Visual Studio下载缓存文件夹（c：\ ProgramData \ Microsoft \ VisualStudio \ Packages），则必须连接只要在Visual Studio中安装外部程序，就可以使用外部硬盘。通常，建议在您的PC中设置VS下载缓存文件夹。卸载VSIX程序（即添加的外部程序）时，还需要VS下载缓存文件夹。没有它，您将无法卸载外部程序。在安装VS时检查VS下载缓存文件夹的保存位置。
