Windows 10 .NET 3.5安装

我在Windows 10的版本9841上。我完整下载了.NET 3.5 SP 1。我双击安装程序，但没有任何反应。.NET版本与Windows 10不兼容吗？我需要它来安装SQL Server 2014 Express。

本文介绍了方法（未经测试）

Insert your Windows 10 DVD, or double click its ISO image, or insert your bootable flash drive with Windows 10, depending on what you have.
Open 'This PC' in File Explorer and note the drive letter of the installation media you have inserted. In my case it is disk D:
installation media drive d
Now open an elevated command prompt and type the following command:

Dism /online /enable-feature /featurename:NetFX3 /All /Source:D:\sources\sxs /LimitAccess

Replace D: with your drive letter for Windows 10 installation media.
dism

To save your time, I have prepared a simple batch file which will save your time and will find the inserted installation media automatically. It looks like this:

@echo off
Title .NET Framework 3.5 Offline Installer
for %%I in (D E F G H I J K L M N O P Q R S T U V W X Y Z) do if exist "%%I:\\sources\install.wim" set setupdrv=%%I
if defined setupdrv (
echo Found drive %setupdrv%
echo Installing .NET Framework 3.5...
Dism /online /enable-feature /featurename:NetFX3 /All /Source:%setupdrv%:\sources\sxs /LimitAccess
echo.
echo .NET Framework 3.5 should be installed
echo.
) else (
echo No installation media found!
echo Insert DVD or USB flash drive and run this file once again. 
echo.
)
pause

.Net Framework应该已经内置到Windows 10中，您可以从控制面板中启用它。

执行以下操作以在Windows 10上启用.Net Framework

1. 按键盘上的Windows+ R键。
2. 在“ 运行 ”命令框中键入“ appwiz.cp l”，然后按“ ENTER ”。
3. 在“ 程序和功能 ”窗口中，单击“ 打开或关闭Windows功能 ”链接。
4. 检查“ .NET Framework 3.5（包括.NET 2.0和3.0） ”选项是否可用。
5. 如果是，则启用它，然后单击“ 确定 ”。
6. 如果出现提示，请按照屏幕上的说明完成安装并重新启动计算机

来自techgainer.com的安装程序称为“ .NET Framework 3.5脱机安装程序”，可帮助您解决此问题。为此，您只需要Windows安装DVD！
