Windows server 2016 , unable to install .net framework

Question

I accidentally removed .net framework 4.5 feature from server manager in windows server 2016 machine. Now I'm not able to open any windows component (server manager , IIS , Powershell ...) where I'm getting this error :

To run this application,you first must install one of the following versions of the NET Framework: v4.0.30319 Contact your application publisher for instructions about obtaining the appropriate version of the .NET Framework.

I tried to install .NET Framework 4.7.1 , the installation finishes successfully , but when I reboot my computer , it turns up that the .net framework is not installed.

When I try to install v4 I get :

Microsoft .NET Framework 4 is already a part of this operating system, but it is currently turned off. To enable the .NET Framework 4 , use Turn Windows features on or off in Control Panel.

But unfortunately I'm not able to access server manager to install the feature.

any help would be appreciated

Solution

Execute the following command on CMD as administrator.

Dism /online /Enable-Feature /FeatureName:NetFx4 /All

I Hope this can help you.
