Hello house, i have bought more than 4 window 7 64 bits software but can't format my laptop with it, given error of file missing/corrupt. pls someone should help me on how and where i can get original window 7 64 bits software to format my laptop Thanks.

Use dvd lens cleaner to clean your dvd drive

@impe, thanks for ur response. Nothing wrong with my drive. The window7 disc has edition of 32 and 64 bits but only its 32bits that is working which i used to format it but my laptop didn't respond well the 32bits so i need window 7 with the 64bits that will format my laptop successfully not the one that will stop formatting with file missing or corrupt in the process of formatting. Thanks.

Did you buy all the softwares in the same place? If your answer is yes then look for another seller because those 300 naira softwares you are buying at computer village are pirated copies and some files might have gone missing during mass copying. But if you buy from different sellers then try cleaning your drive or better still take your laptop to the software seller he will install it for you. Does your laptop have requirement for windows 7 16bit? That is dual core processor minimun and 4gig ram
