How to install net framework 3.5 in windows 8 & 8.1
You can enable the .NET Framework 3.5 yourself through Control Panel. In Control Panel search for “Turn Windows features on or off”, and then select the “.NET Framework 3.5 (includes .NET 2.0 and 3.0)” check box. This option requires an Internet connection. You do not need to select the child items for Windows Communication Foundation (WCF) HTTP activation unless you are a developer who requires WCF script and handler mapping functionality.
Turning Windows features on or off in Control Panel
- If your computer is not connected to the Internet or you want to install it offline. You can enable the .NET Framework 3.5 by using the Deployment Image Servicing and Management (DISM) command-line tool and specifying the installation media (ISO image or DVD) you installed Windows 8 – 8.1 from.
- In Windows 8 or Windows Server 2012, open a Command Prompt window with administrative credentials (that is, choose Run as administrator).
- To install the .NET Framework 3.5 from installation media located in the D:\sources\sxs directory, use the following command:
DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:d:\sources\sxs
Where:
- /Online targets the operating system you're running (instead of an offline Windows image).
- /Enable-Feature /FeatureName:NetFx3 specifies that you want to enable the .NET Framework 3.5.
- /All enables all parent features of the .NET Framework 3.5.
- /LimitAccess prevents DISM from contacting Windows Update.
- /Source specifies the location of the files needed to restore the feature (in this example, the D:\sources\sxs directory).
