Visual Studio 2017 RC安装错误0x80131500无法反序列化包

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空间,第一次尝试在下载期间失败.之后每次尝试安装它会导致以下错误/激发:

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

我已经尝试过:

• 再次下载并运行安装程序
• 手动删除C:\ Program Files(x86)\ Microsoft Visual Studio*
• 已删除已安装的新组件(Core Framework,Win SDK等)
• 卸载Visual Studio 15预览

我假设安装程序无法获取已安装产品的信息.在重复之前的一行:

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

我已经知道,失败的Visual Studio安装有时会如此混乱,只有重新安装操作系统才能解决问题.但在我这样做之前,也许有人有一个解决方案或提示 - 基本上它只是一个json解析问题...

原始解决方案: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

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

是问题.json解析错误很明显.我重命名/删除了文件,设置就像一个魅力.
