    Hmmmm...............look at the chart halfway down this link:

    Windows 7 editions - Wikipedia, the free encyclopedia

    where it says, next to "64-bit version available?", under the Home Basic column, "Yes, but not in retail SKUs".

    That makes me wonder about the validity of what you have downloaded.

    Get your money back on that one. :)

    I believe the answer to your question is no.

    It is perfectly possible to install Home Basic 64-bit using a Retail disk, and activate it using the Key from your 32-bit install.
    ALL windows 7 Keys are valid for both 64-bit and 32-bit installs of their assigned edition - but only one at a time!
