Good day mate
Highlight this serial number on top and make sure you have got everything highlighted and press (ctrl + c)to copy the highlighted serial,then open WinX Blu-ray DVD to ipod/iphone ripper and in registration code you can click the code and delete everything in it,make sure box is completely empty .Then click on the box again with your mouse ,and the right click and go to paste and click on it.No the number should be in the registration box and then click on the register box to register.Good luck.I am running Win7(64 bit)works fine for me
