My computer has been crashed and due to which I have lost the old hard drive, so I gone to the market and brought the new hard drive. When I have fixed the new hard drive and install the Microsoft Office 2010, then it was not getting installed on it. I am also having the product key of it, then also it is not been installed. So please suggest me what so I do and how to solve this problem also. As I want to use the Microsoft Office for the work which I do daily. Please suggest me what to do on this problem. Thank you all.
