问题描述

请帮助 我可以安装.net framework 3.5，没有任何错误，当我打开或关闭Windows功能时    .net Framework 3.5已列出并取消选中。

当我检查它并单击确定它会去在框中说搜索所请求的功能，然后它说  Windows完成请求的更改。 Windows需要重新启动您的PC才能完成所请求的更改安装。 

我重启了PC。

然后检查打开或关闭Windows功能，它又回到列出状态但未选中。

我一遍又一遍地移除并重新安装.net框架3.5和同样的事情 

是的我正在使用管理员权限执行此操作

我复制了microsoft-windows-netfx3-ondemand-package.cab文件到安装文件夹并运行

Dism.exe / online / enable-feature / featurename：NetFX3 / source： C：\ install / LimitAccess

我收到消息"操作已完成，但未启用NetFx3功能。"

请帮助我和需要安装的应用程序

解决方案

嗨朋友，

欢迎来到MSDN论坛。

请看一下这个博客：

.NET Framework安装验证工具用户指南并下载.NET Framework安装验证工具以验证.NET Framework 3.5。

您可以尝试关闭计算机并再次开始检查其状态。

最好的问候，

Please help  I can install .net framework 3.5 with no errors and when I go to Turn Windows Features on or off   .net Framework 3.5 is listed and unchecked.

When I check it and click ok it goes to the box saying searching for requested features, then it say's  Windows Completed the requested changes. Windows needs to reboot your PC to finish installing the requested changes. 

I restart the PC.

And then check turn windows features on or off and it's back to being listed but unchecked.

I removed and reinstalled .net framework 3.5 and same thing over and over 

Yes I'm doing this with Admin rights

I copied the microsoft-windows-netfx3-ondemand-package.cab file over to an install folder and ran

Dism.exe /online /enable-feature /featurename:NetFX3 /source:C:\install /LimitAccess

I get the message "The operation is complete but NetFx3 feature was not enabled."

I restart go to enable it in windows features and the same thing installs with no errors and say restart and so I do and then it still shows unchecked.

Please help I have and app that requires this to be installed

解决方案

Hi friend,

Welcome to the MSDN forum.

Please have a look at this blog: .NET Framework Setup Verification Tool User’s Guide and download the .NET Framework setup verification tool to verify the .NET Framework 3.5.

I tried to check those 2 options under .NET Framework 3.5 (includes .NET 2.0 and 3.0) to install, it completely without any error, not requires restarting the computer and check it again like the following:

You can try to Shut down the computer and start to check its status again.

Best regards,

Sara
