Upgrading error to Win 7 Pro from Win 7 Home Premium

Hi,
Recently I bought new laptop with an Intel I5 microprocessor 64bit. It came with Microsoft Home Premium installed on it. I just purchased Microsoft 7 Professional and after downloading it I tried to install it, it immediately stops and shows me following:

ERROR 0x80070002 cannot findboot.wim file
Therefore the system is stuck and upgrade cannot be done. Does anyone else have same problem and know how to fix this? Any suggestion is welcome. Thanks in advance.
