Setup error :Attempted to perform an unauthorized operation SQL Server 2014
In my Case, creating an Administrator Windows Account and installing SQL Server worked!
Also you can simply activate the built-in windows Administrator Account by running the net user administrator /active:yes command in command prompt(Admin Mode), then log in as Administrator. Now You can Install SQL Server without problem.  

Afterwards you can use SQL Server from your own normal windows account after installation. 

I would recommend deactivating Administrator account by running net user administrator /active:no command in command prompt(Admin Mode)
