无法安装.NET Framework 3.5 [英] cannot install .NET Framework 3.5

问题描述

我已经安装了微软的Visual Studio 2008 SP1和VS 2010 SP1。我使用Windows 7。

I already have installed Microsoft Visual Studio 2008 SP1 and VS 2010 SP1. I'm using Windows 7.

然后，我发现在我的控制面板中安装的程序，只有下面分别安装.NET框架：

Then, I noticed in my Installed Programs in Control Panel that only the following were the installed .NET Frameworks:

• 在微软.NET Compact Framework的2.0 SP2
• 在微软的.NET Compact Framework 3.5的
• 的Microsoft .NET Framework 4客户端配置文件
• 的Microsoft .NET Framework 4扩展。

出于某些原因，当我安装PowerCommands为Visual Studio 2008，它说，我需要安装.NET Framework 3.5。

For some reasons, when I was installing PowerCommands for Visual Studio 2008, it says that I need to install .NET Framework 3.5.

当我试图使用dotnetfx35.exe，它只是解压安装，但不会继续安装过程。

When I tried to use dotnetfx35.exe, it just unpacks the installer, but doesn't proceed with the setup process.

这只是因为我使用的是Windows 7？或者是有设置的.NET Framework 3.5的正确方法？

Is this just because I'm using Windows 7? Or is there a proper way of setting up .NET Framework 3.5?

谢谢！

推荐答案

较新的操作系统（Windows 7+据我所知）没有（不能）使用安装文件.NET 3.5框架。另外，3.5的框架并不一定显示在添加/删除程序。相反，你打开的功能。另一个细节是，.NET 3.5包括3.0和2.0框架。换句话说，.NET框架3.0和2.0不需要单独安装。

Newer operating systems (Windows 7+ afaik) do not (cannot) use installation files for the .NET 3.5 framework. Also, the 3.5 framework does not necessarily show in add/remove programs. Instead, you "turn on" the feature. Another detail is that .NET 3.5 includes 3.0 and 2.0 frameworks. In other words, .NET framework 3.0 and 2.0 do not require separate installs.

要添加/验证安装的.NET 3.5在Windows Server 2008 R2的：

To "add"/verify installation of .NET 3.5 in Windows Server 2008 R2:

转到控制面板>程序> Windows功能打开或关闭>   角色>添加角色服务（小按钮关闭的权利）>确认   .NET框架3.5.1复选框>单击下一步，直到你可以点击   安装。

Go to Control Panel > Programs > Turn Windows Features on or off > Roles > Add Role Service (little button off to the right) > Ensure ".NET Framework 3.5.1" is checked > Click "next" until you can click "install".

这个过程应该是在Windows 7相似。

The process should be similar in Windows 7.
