Hello,
Recently I tried to install Windows 8. I have had Windows 8 on my Laptop before but I reformatted my computer and had a Windows 7 disk and decided I'd put that back on then upgrade to Windows 8 as I don't have a Windows 8 disk and only have a Windows 7 disk. So I followed Microsofts instructions found on this page: here and downloaded the Windows 8 Installer and entered my product key and everything was fine and then I downloaded Windows 8 but got an error when it was preparing the download for installation.
Here's a screenshot of the error:

If anyone could provide any assistance I'd greatly appreciate it.
My laptop is an Acer Aspire v3-771, 64 bit
Currently running Windows 7
