如何修复DNX / DNVM在Visual Studio 2015年？

问题描述

今天，我在Windows 7 64位系统安装了VS 2015年。主要是测试新的.NET的核心功能和等，并测试我创造了新的C＃控制台应用程序（包）的解决方案，得到了这样的信息：

Today I installed VS 2015 on Windows 7 x64. Mainly to test new .Net Core features and etc. And for test I created new C# "Console Application (Package)" solution and got this message:

DNX S​​DK版本DNX-CLR-双赢x86.1.0.0-beta5的安装失败。该解决方案将使用DNX S​​DK版本DNX-CLR-双赢x86.1.0.0-beta5的本次会议。

我不能编译和调试项目。此外，在项目的属性时，我已经打开调试选项卡，然后VS崩溃了。

I can't compile and debug project. Also, when I have opened debug tab in project properties then VS crashed.

DNVM输出，当我打开的解决方案：

DNVM output when I opened solution:

Invoke-Command : The term 'x86' is not recognized as the name of a cmdlet, func
tion, script file, or operable program. Check the spelling of the name, or if a
 path was included, verify that the path is correct and try again.

任何想法如何解决这个问题？

Any ideas how to fix it?

另外，我有previously安装了VS 2015 preVIEW和DNX / DNVM分开。但我认为，我的VS 2015年安装前彻底清除它。莫非这在某种程度上影响了当前VS安装？

Also, I have previously installed VS 2015 Preview and DNX/DNVM separately. But I think, I completely removed it before VS 2015 installation. Could this somehow affects current VS installation?
