If you put them into the Updates folder,it most probably put the includes folder in there.You can go in and delete that if you like,though there is probably no harm in it being there.
Navigate to your friends main drive,which is probably C:\,then go to Program Files\Spybot - Search & Destroy,then open the Updates folder and delete the Includes folder.
Now,for the Manual Updates,doubleclick spybotsd_includes.exe,click the browse button,and navigate to C:\Program Files\Spybot - Search & Destroy\,then click OK,then click install,and you should be good to go for the detection updates.
You should probably also download and transfer this manual update,if you haven't already,otherwise you may get an error when doing a scan with Spybot.
