Windows 8.1 problem in Fusion

Hi all,
I am trying to install my Windows 8.1 ISO file on my Macbook Pro with VMFusion V7. Each time I initialize the installation I receive the message that there is file missing or corrupt with the code 0x80070570. I tried with ISOS already on the HD. I do not have any blank DVD's at the moment, but still to make sure that it will make any difference if I tried installing from the DVD? Actually I am not sure if this is related to it, but I had the same problem with the Talking Installation of Windows 7 in Bootcamp, though I am not sure of the error code. Many threads on other forums suggest hardware problems: faulty RAM, bad sectors, none sounds possible as the machine with Yosemite is just running great.
Thanks.
