Visual Studio 2017 RC 安装错误 0x80131500 反序列化包失败

Question

我正在尝试在我的机器上安装新的 Visual Studio 2017 RC。由于没有足够的可用磁盘 space，第一次尝试下载失败。之后，每次尝试再次安装它都会导致以下 error/excpetion:

2016-11-17T16:50:08 : Error : Failed to get installed product summaries. [installerId: SetupEngine, error: JsonReaderException at    bei Newtonsoft.Json.JsonTextReader.ReadStringIntoBuffer(Char quote)

我已经试过了：

再次下载并运行安装程序
手动删除 C:\Program Files (x86)\Microsoft Visual Studio*
删除了已安装的新组件（核心框架、Win SDK 等）
已卸载 Visual Studio 15 预览

我假设安装程序无法以某种方式获取已安装产品的信息。异常前一行：

2016-11-17T16:50:08 : Verbose : Getting product summaries. [installerId: SetupEngine]

我已经知道失败的 Visual Studio 安装有时会非常混乱，只有 OS 重新安装才能解决问题。但在我这样做之前，也许有人有解决方案或提示 - 基本上是 "just" 一个 json 解析问题...

Answer 1

原方案： https://developercommunity.visualstudio.com/content/problem/2877/install-error-0x80131500-failed-to-deserialize-pac.html

Elliot Cooley (state.json) 提到的文件在

下找到

%ProgramData%\Microsoft\VisualStudio\Packages\_Instances\<instance> where "instance" is an 8 character Hex string.

是问题所在。 json 解析错误很明显。我 renamed/deleted 文件和设置工作得很好。

Answer 2

我不得不删除 8 个字符的十六进制字符串文件夹，然后它起作用了。

%ProgramData%\Microsoft\VisualStudio\Packages\_Instances\
