I know this is a little close to the Windows 10 Free Upgrade offer but though I would post it anyways.  I have succesfully "upgraded/downgraded" to Windows 7 Professional SP1 64bit from Windows 7 Enterprise SP1 64bit.  I did not run the tool but rather updated the registry keys manually as suggested by: dynabase below.  I did both the 32bit and the 64bit keys:

Original:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\EditionID "Enterprise"
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProductName "Windows 7 Enterprise"
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\EditionID "Enterprise"
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\ProductName "Windows 7 Enterprise"

Modified:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\EditionID "Professional"
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProductName "Windows 7 Professional"
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\EditionID "Professional"
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\ProductName "Windows 7 Professional"

Then without rebooting after updating the registry I did as eccrk suggested and just ran Setup.exe from my bootable Windows 7 Professional SP1 64bit USB key.  I did not reboot using the key.  I then followed the on screen prompts and chose the Upgrade option, also I opted not to get the latest updates from Microsoft.

It then did its install / Upgrade.  All is good.  Thx for all the posts on this forum.

I have Windows 7 Ultimate x64 installed on my laptop and fully updated. I want to downgrade to Pro since I have a valid license which I can now use. Can I downgrade with this tool and use the original Win 7 Pro DVD? Or do I need to download some latest Win 7 Pro x64iso? From where? I also have an AIO x86-x84 Win 7 iso and tried to run it from virtual drive but it does not run. Not sure if I can use this??

Ok, so I too was hoodwinked with a bogus Windows 7 Enterprise pc when I had my pc upgraded at a show.  Now started (over a year later) getting the MS warnings.

I do own the previous Windows 7 Ultimate software and want to "downgrade" to a valid version of 7 Ultimate (actually my favorite MS OS).

I get the same error mentioned below, "Your current version of Windows is more recent than the version you are trying to upgrade to. Windows cannot complete the upgrade. "

I could really use some guidance here!

Thanks.

I find the same thing with trying to downgrade Windows 7 Enterprise 64-bit to Windows 7 Professional 64-bit.

After letting the tool modify
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\EditionID to "HomePremium"
   and
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProductName to "Windows Home Premium"

and manually modifying
  HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\EditionID to "HomePremium"
  and
 HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\ProductName to "Windows Home Premium"

I also get "Windows 7 Enterprise cannot be upgraded to Windows 7 Professional" when I tell the installer to perform an upgrade. I'll also point out that even with these registry changes, the running OS still identifies itself as Windows 7 Enterprise 64-bit.

I went in to regedit and edited both 

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion

Change the Edition ID Key to "Professional"
Change the ProductName Key to "Windows Professional"

and went back to the Media Creation Tool downloaded straight from Microsoft's website and clicked upgrade and it worked 100%

I have windows 7 professional 64 bit installed and I need to downgrade to home basic 64 bit which I have the license for (OEM version came preinstalled with my laptop).

I have downloaded a multi-editon DVD from the net and made necessary changes in the registry both 32 bit and wow6432node keys.

However when I try to upgrade from the dvd, the compatibility check results with this 2 errors in the same page: "64 bit version can not be upgraded to 32 bit" and "32 bit version cannot be upgraded to 64 bit".

I am definitely sure that I have 64 bit pro and installing 64 bit home basic. I also tried with a single edition homa basic 64bit dvd which resulted with the same error!

What may be the reason? Any ideas would be highly appreciated...

Confirming this works, 8/21/2015:

If you are using Windows 7 Enterprise 64 Bit then you must manually change the text in the registry at:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion

Change the Edition ID Key to "Home Premium"
Change the ProductName Key to "Windows Home Premium"

I then inserted my OFFICIAL Windows 7 Professional 64 Bit installation DVD and pressed "Install" then later "Upgrade".  

Awesome comments below got me to this point, one machine downgraded, the second machine at 42%.  All credit to the guys below.  I'm wondering if this change (above) is all that is needed for the upgrade anyway, and file download on the right and above just changes these registry values for you?

Just for the sake of precision, I believe that for Home Premium, 
the Edition ID ought to be "HomePremium" rather than "Home Premium" and 
the ProductName ought to be "Windows 7 Home Premium" rather than "Windows Home Premium".

If this is incorrect, then please let me know. 
I'm just going off of screenshots in others' tutorials.

For all you 64-bit people out there,mortybrown's fix works.
There are three other things to keep in mind whatever your install
i) My system disk was encrypted with Truecrypt so as a precaution I decrypted it before I started the process
ii) MP7000 says above "insert you Install Disk you buy and click Install". It's tempting to think after the registry changes you should reboot off the Install DVD. This is not what he is saying - don't reboot, just run the Install from the DVD as Administrator - depending on which version it may be called Setup.exe
iii) Even after you have installed your new License Key the process is not over. After yet another reboot you will need to go to Control Panel\All Control Panel Items\System, Windows Activation and click on the blue link there. This initiates the process that verifies your license key.

Any advice on how to get past this problem?

I was wrong.  The mortybrown solution below does work.  The issue I had was with the first Windows ISO I tried to use.  It did not have SP1 on it and my installed OS did have SP1 installed.  This solution only works if the service pack matches on the ISO and the installed OS.  To state it another way if your installed OS has SP1 installed the ISO you use must also have SP1.  If it does not you will get errors and it will not update.  The bottom line is the ISO must have the same or higher Service Pack level before you can downgrade.  If your ISO does not have SP1 you can uninstall SP1 from your OS and it will work. 

I have done two computers so far and the downgrade worked perfectly.  Keep in mind you will need a valid Software Key to reactivate the new windows version once it is installed.  If you have a version of Microsoft Office installed the first time you log in you will get an error stating it is not a registered copy.  When that happens just click on register online option and it will find the key and register it properly.  No need to find the Key again because it is still on your machine.

The downgrade tool edits the correct registry path for Win7 32 bit version by changing nothing else than:

   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\EditionID
   and
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProductName

to the values you request inside the tool  (Windows Version you are installing).

If you use Win7 64 bit however then execute the tool and additonally change the EditionID and ProductName values in
   HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion

Thanks mortybrown.  You saved my tail with your post.  I could never get this tool to download.

I don't know what you're doing wrong, i click on the Download symbol and the download opens immediately.
Here's an alternate download site:
www.softpedia.com/get/System/O…

But you will still need to change the registry values for the 64 bit windows version by hand (but you can copy it from the 32 bit part the tool does for you).

I found the solution why this works sometimes and sometimes not on www.unawave.de/installation/do…
-> It works only for 32 bit version of win7 and not 64 bit version.

Workaround:

The downgrade tool edits the correct registry path for Win7 32 bit version by changin nothin else than:

   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\EditionID
   and
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProductName

to the values you request inside the tool.

If you use Win7 64 bit however then execute the tool and additonally change the EditionID and ProductName values in
   HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion

Tested that and was able to run the upgrade from CD afterwards on my 64 bit Windows.

Thanks for the reply.  It would be nice if that article was in English.  I would still like to know why I can't download the file from this site.  Since it is probably just a script if someone has this software maybe they could print out the script since we can't download it.
