Where is the Windows 8 Pro 64-bit ISO download?

Question

Normal tech support has yet to answer this problem.  I purchased the $39.99 Windows 8 Pro download, and ran the upgrade on my Windows XP Home Edition (which is 32-bit OS, by design) machine.  The machine is fully capable of a 64-bit OS (in
fact, I have a dual boot with Ubuntu 12.04 LTS 64-bit running in a separate partition).  When I finished the Windows 8 Pro install, it turned out to be the 32-bit version.  I discovered via the normal support forum that this is a limitation of the
download installer - it chooses without user option the architecture based upon the older Windows version.
I called support and they first thought that the MS store could provide the 64-bit ISO download.  That didn't work - they're researching it, though.  I tried support again and this time the rep said the installer chooses the architecture based
on what the machine is capable of running.  I respectfully disagreed, but that didn't solve my problem.
So, how can I get the 64-bit ISO download, without having to make an ADDITIONAL purchase of the retail DVD version?

Answer 1

I attempted to get this problem resolved and entered the truly bizarre world of Microsoft "Support."
The Windows 8 support line took my information, repeatedly put me on hold and then transferred me to another department.    I was again asked for all my information, again put on hold repeatedly and then transferred to a third department. 
I ended up with a recording saying my call couldn't be completed and was sent back to the 1st support department. 
I spent the next 15 minutes again repeatedly being put on hold and I eventually asked for a supervisor who again wanted all my information.  At this point I had been on the phone with Microsoft for over an hour and had gotten nowhere so I asked for
a refund.  The supervisor said she would process one asked me to go to a web page and click on a link that did not exist on that web page.  She spent the next 15 minutes putting me on hold and then returning to the call only to again insist I click
on the non-existent link.
Eventually she figured out that there was a problem with Microsoft's web page and said I would get a call back within 48 hours.  72 hours later I had received no call.
I again called the Windows 8 support line.  After 20 minutes I was told that I was calling the wrong department (I had spent over an hour on the phone with them previously) and given another phone number.  I called the 2nd phone number and was
given a 3rd phone number. When I called the 3rd number I was given the 1st number once again. 
I had spent over 2 hours on the phone with various Microsoft departments and ended up literally right back where I started.  I ended up disputing the charge with my credit card company and contacting the Attorney General.
I can happily say that my experiance was the opposite they were freidly and helpfull told me I would need a refund as the 32 Bit Key Code would not work for a 64 Bit download ? rather odd as it was the same code for both 32 and 64 Bit versions discs when I
installed Win 7, and they gave me a web link that took me to my purchase information and I had to Click on the refund link, the email regarding my rufund was in my inbox by the time I had completeed doing the required steps on the web link, the email also
had a link for this same web siteI had visited as well. simple and painless, very stisfied with the helpline, OK so not being warned about it only going to download a software ISO etc. for the present 32 or 64 Bit operating system was annoying and while
a well meaning idea to ensure a simple upgrade was flawed, but easy to get round.
