Writing to Registry: How do I acquire the proper permissions?

Application.UserAppDataRegistry.SetValue("name", "value");

This microsoft article says I nead proper permissions (read, write, create), but it gives no information on how those permissions are specified! :(

I need to know how to acquire proper permissions to use code such as the above.

Thanks,
