microsoft.net.framework2.0？Win10无法安装Microsoft. NET Framework2.0解决方法

大家好,今天小编来为大家解答以下的问题，关于microsoft.net.framework2.0，Win10无法安装Microsoft. NET Framework2.0解决方法这个很多人还不知道，现在让我们一起来看看吧！

Win10无法安装Microsoft. NET Framework2.0解决方法

Win10无法安装Microsoft.NET Framework2.0的解决方法主要包括以下几个步骤：

1.通过Windows Update服务解决：按“win”+“R”键打开运行窗口，输入“services.msc”并按回车键，找到Windows Update服务并停止它。再次打开运行窗口，输入cmd并以管理员身份运行，输入“net stop WuAuServ”并按回车键停止更新服务。进入Windows目录，找到SoftwareDistribution文件夹并将其重命名为SDold。重新启动Windows Update服务，并尝试安装Microsoft.NET Framework2.0。

2.通过控制面板安装：打开控制面板，选择“程序和功能”。点击“启用或关闭Windows功能”。在Windows功能对话框中，找到并勾选“.NET Framework 3.5”。点击“确定”按钮进行安装，耐心等待安装完成。

3.清除已安装的.NET Framework版本：如果安装过程中遇到错误或冲突，如系统提示已经安装了更高版本的.NET Framework导致不兼容，可以使用Microsoft.NET Framework删除工具来清除已安装的版本。或者手动删除C:WINDOWSMicrosoft.NETFramework目录下的相关文件和注册表项。

注意事项：在进行上述操作前，建议备份重要数据。由于操作系统和软件的复杂性，建议在官方网站或专业人士的指导下进行操作。如果以上方法仍然无法解决问题，建议寻求微软官方或专业技术人员的帮助。

net framework 2.0 是什么

.NET Framework是支持生成和运行下一代应用程序和 XML Web services的内部 Windows组件。

.NET Framework现主要由以下几部分组成:

(1).包括五种正式的语言编译器(C#,Visual Basic,托管 C++,J#和Jscript脚本语言等).

(2).框架类库(Framework Class Library,FCL)由很多相关互联的类库组成,支持Windows应用程序.Web应用程序.Web服务和数据访问等的开发.

(3).公共语言运行库(Common Language Runtime,CLR)是处于,NET核心Framework的面向对象的引擎,其将各种语言编译器生成的中间代码编译为执行应用程序所需要的原生码(native code).

NET Framework主要包含一个非常大的代码库，可以在客户语言(如C#)中通过面向对象编程技术(OOP)来使用这些代码。

目的是，不同的操作系统可以根据自己的特性，支持其中的部分或全部模块。例如，PDA支持所有的核心.NET功能，但不需要某些更深奥的模块。

经查证，win xp pro和home版本有可能会出现此问题，除会发生以上现象外，当您尝试在“控制面板”中打开“管理工具”时，可能不会执行任何操作。

问题的原因在于注册表设置不正确

解决方法：

2.找到以下注册表项：

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders

3.在“注册表编辑器”的右窗格中，双击常见管理工具。

4.在“数值数据”框中，键入以下行，然后单击确定：

%ALLUSERSPROFILE%\Start Menu\Programs\Administrative Tools

5.在文件菜单上，单击退出以退出注册表编辑器。

6.重启电脑。

如果以上办法无效活着在你的系统上找不到对应注册表键值时，把以下所有内容复制到文本文档，保存为注册表文件*.reg，双击导入。
