Hello. I have a Inspiron N5050 and used it for about 3 or 4 years now. It worked very slow so i decided to reinstall it. A friend had a disk with windows 7 home premium (that's what i also had) but after the installation i realised he had a 64 bit version so i got on the internet and downloaded a windows 7 home premium 32 bit. But now i need to enter the product key and now i get the message that it's invalid (or something like that). Does anyone know what the problem is?
