Reboot your computer and try installing the NET Framework. If still getting the same error message then try following the below-given steps. Open CMD (Command Prompt) in administrator mode. In the command prompt window, type the following command “net stop wuauserv” and press the enter button to stop the service.
You do not have sufficient privileges to complete this operation for all users of this computer. Log on as an administrator and rerun Setup. You must be an administrator on the computer to install the . NET Framework.
Here we show you how to solve this issue. First, you can check if the component is already installed on your device. Go to Control Panel > Programs > Turn Windows features on or off, verify if . NET Framework 3.5 checkbox is selected and then proceed with the software installation.
Another Solution is to:
