感谢您的帮助。谢谢

它也可能与VS 2015更新3有关。如果您首先安装了Update 3,则a表示无法删除与VC++可再发行文件相关的注册表项

您需要进入程序和特性,右击->更改->修复最新Visual C++ 2015可重分发版本(版本140.24123)

的x64和x86版本。
这对我来说很有效,然后我成功地安装了.net core RC 2和VS工具预览。

我也有同样的错误,但能够卸载ASP.net RC1。我按照链接,它说它无法下载,并成功下载文件,并安装了它。。。但现在我不确定我的安装处于什么状态。它显示在“程序和功能”窗口中,如已安装。。。但是..我不得不卸载VS2015并重新安装。我想我在安装rc2时搞砸了。这解决了我的问题。如果有帮助的话,尝试从这里使用msi!这可能是正确的,因为我也首先安装了VS2015更新。我无法验证这一点并将其标记为应答,因为我已经为此卸载并重新安装了VS2015。
