Nope, the only one and it's not a requisite it's a dependency, which is .Net 4.0

@gameranddev: It's not only your problem, it's a badly written keygenme.

ManagementClass managementClass = new ManagementClass("Win32_NetworkAdapterConfiguration");

string text = "";

ManagementObjectCollection instances = managementClass.GetInstances();

This code throws an exception when you run it on a computer without any network adapter. For example, inside VMWare.
