请参阅 Visual Studio 安装屏幕中的错误消息。您直接安装 Visual Studio 2015 update 3，它只是 Visual Studio 的更新，它适用于已安装任何 Visual Studio 2015 版本的计算机。

您需要下载带有更新 3 的 Visual Studio 2015 community/enterprise/profession 才能安装，请访问 Download older versions of Visual Studio 并单击“加入”现在免费 >' 如果您没有订阅帐户。使用您的 Microsoft 帐户登录并加入 Visual Studio Dev Essentials，然后单击“下载” 菜单并使用关键字搜索，然后您将得到如下结果，单击您需要的 Visual Studio 2015 版本并找到下载 link 进行下载。它应该可以工作。
