Microsoft NET Framework Installation problem Error Code 0x800c0006 Fix

.NET Framework 4 is mandatory for developers and end users to run the latest build of applications on Windows. But, while downloading-installing the .NET Framework 4, many users have complained that the installer is stalling midway, showing up the following error message – “.NET Framework 4 has not been installed because Download failed with error code 0x800c0006“. While installing the .NET Framework 4 on your device, if you are also experiencing it, you have just gotten into the right place.


Fix 1 – Check the network connection

The first thing you should check is whether the system has a stable network connection. .NET Framework 4 connects to the internet and download the package file to install it.

1. Close the .NET Framework installer page.

2. Then, disconnect the system from your WiFi network. Turn off the router.

If you are using a LAN cable, you have to unplug it from your computer.

3. Then, wait for 2-3 minutes. Then, turn ON the router.

4. For Ethernet users, plug in the ethernet cable to your system.

5. Connect your system to the WiFi network.

Then, run the .NET Framework 4 (Web Installer) and follow the on-screen instructions to complete the installation process.


Fix 2 – Run the offline installer

Download the offline installer for the .NET Framework 4 package and install it on your computer. No need to worry about network failure at all!

1. Go to the .NET Framework 4 (Standalone Installer).

2. Once you are there, click “Download” to download the installer.
