Cant install Mission Planner

Hi,

When trying to install mission planner on my Windows 8.1, I get the message that says I need Microsoft .net framework 4.0. When installing .net framework 4.0, I get the message that it is already a part of my operating system and I do not need to install it.

How should i proceed?

Hello, install .net framework 4.6.1 or higher version

… what can I do?

Probably the easiest way is try to download and apply every update from Windows Update in control panel.
According to https://support.microsoft.com/en-us/help/2919355/windows-rt-8-1--windows-8-1--and-windows-server-2012-r2-update-april-2

Note The update for Windows RT 8.1 can be obtained only from Windows Update.
