Enable Windows \ Role feature via Installshield

Our application is supported for OS 'Windows server 2012 R2'. We have an application in which we need to enable the "Application Initialization" function. We used Installshield 2014 to install our app installer. I found an implementation to check the status of any Windows function. I tried the following code which gave me a list of installed features:

ManagementClass objMC = new ManagementClass("Win32_ServerFeature");
ManagementObjectCollection objMOC = objMC.GetInstances();
string featureName = string.Empty;
var AppInitFeature = (from ManagementObject objectFeature in objMOC
                      where objectFeature.Properties["Name"].Value.ToString() == "Application Initialization"
                      select objectFeature).First();

      

        
        
        
      

    

Here's my question: Is there a built-in capability in installshield to enable a Windows feature? OR we need to write any custom action for this. If we need to write our own action then how to enable Windows feature using C # code.

Can anyone help me on this.

Thanks in anticipation.
