Workaround to Upgrade from 32-Bit (x86) to 64-Bit (x64) Windows 7 Operating System
Direct upgrade from 32-bit (x86-based) operating system of either Windows XP, Windows Vista or Windows 7 to 64-bit (x64-based) Windows 7 OS is not a supported upgrade paths to Windows 7. When user tries to run 64bit setup.exe Windows 7 installer from within 32bit operating system, the following error message will occur.

The version of this file is not compatible with the version of Windows you’re running. Check your computer’s system information to see whether you need an x86 (32-bit) or x64 (64-bit) version of the program, and then contact the software publisher.
So how to “upgrade” from 32-bit OS to 64-bit Windows 7?
Unfortunately, there is no direct way to perform an in-place upgrade from 32-bit operating system such as x86 Windows XP or x86 Windows Vista to x64 Windows 7, with existing application programs and data retained. The only way to install x64-based Windows 7 on existing 32-bit Windows installation (or vice versa to downgrade from 64-bit to 32-bit OS), is to do a clean install, which indicated by “Custom (advanced)” installation during set up Windows 7 installation wizard.
Here’s the brief guide for user who wishes to upgrade to 64-bit platform from a 32-bit Windows:
- Backup and save existing application settings and data to migrate to new system with Windows Easy Transfer. Note that installed programs won’t be migrated or ported over to new Windows.
Alternatively, just manually do a backup and copying of all data files and personal documents, photos, images, videos, bookmarks and etc.
- Boot and start up computer using the 64-bit (x64) Windows 7 installation DVD disc media or a Windows 7 install USB key flash drive. Setting correct device boot sequence may be required at BIOS. Check out how to access BIOS.
User who has Windows 7 ISO should burn the image to a physical disc with a CD/DVD optical burning software such as Nero and Ashampoo Burning Studio, or uses official Windows 7 DVD/USB ISO Download Tool to create bootable Windows 7 USB flash key drive or write to DVD. In Windows 7, it’s also possible to burn the ISO direct from Windows 7 Explorer without third-party software.
- When prompted by Set up Windows installation wizard, select Custom (advanced).
User is free to create, delete, modify, create or format partition volumes and hard disk drives before continuing the setup installation of Windows 7. If user choose to install over a partition or drive with existing Windows, user will be informed that current installation of Windows will be moved to Windows.old directory.
- Install and activate Windows 7 as usual.
User with x86 setup1.box and setup2.box ESD Windows 7 installation files or x64 setup1.box and setup2.box ESD Windows 7 installation files should follow steps to create and make a bootable ISO prior to burning.
Tip: For end-user with a Windows 7 upgrade license, media and product key, an existing installation of Windows must exist for the upgrade version product key to be able to entered and activated properly. Thus, do not format the hard disk drive prior to loading the Windows 7 setup even if you intend to clean install, or else user has to use hack to complete the clean install the Windows 7 Upgrade. User can create or delete hard disk drive or partition during the setup via Custom (advanced) -> Drive options (advanced) option (note: a 100 MB system reserved partition may be created by Windows 7 Setup), or let Windows 7 install wizard backup the existing configuration to Windows.old folder, and then delete and wipe clean the whole partition volume prior to install Windows 7.
32-bit setup installer can be read and run in 64-bit operating system, but the in-place “downgrade” is equally not supported, with the following error been shown in compatibility report after a run of compatibility check:
The following issues are preventing Windows from upgrading. Cancel the upgrade, complete each task, and then restart the upgrade to continue.
You can’t upgrade 64-bit Windows to a 32-bit version of Windows. To upgrade, obtain a 64-bit version of the installation disc, or go online to see how to install Windows 7 and keep your files and settings.
The above workaround to clean install Windows 7 works to downgrade from 64-bit to 32-bit Windows 7 too.

mi problema es que tengo windows7 x64 en mi computadora y quiero instalar XP de x86 y no me deja, ya investige algunas fuentes pero no me da resultado!! siempre falla de alguna manera.. con enlite ya mero salia pero no medeja guardar los archivos que puedo hacer!!
I read a little of your article and from what I've got it sounds like you want to run programs from a 64 bit onto a 32 bit but my problem is the opposite.
I have hte opposite problem.
I want to run Land Before Time Activity Center but I get the non compatabile message…………even if I use Win XP service mode on the compatible mode.
I wish there =was an answer as Dos Box will not take this game.
this whole post is the biggest joke, pure BOLLOX!
Hello anyone.I'm from Azerbaijan.Windows 7 ordinary key please give me.Thanks from now.
this must be a joke.
In fact, just emailed the host to remove this article as it is rubbish.
I agree with Mike, what's the point of this article? This is in no way a workaround to get around doing a clean install. Your process describes a backup with a clean install. Duh.
At the end, brought up a small question.
your totally right about the small catch you have to BOOT up in 64 bit in order to install windows 64.
Ok, I'll give you that, as a given.
But you mentioned booting up on a flash drive.
provided you copied the image files from the windows 64 to a safe area in the new partition, D://Cab etc. etc. then booted up using the flash drive, and then transferred to D://Cab and run setup.
Would that be a possibility?
Steps:
format secondary partition NTFS
Set flash drive to boot into Windows 64 OS
Boot transfer to D://Cab
Run setup as it is
Just am curious. Have known long time with Windows, any windows, 98-Me-Xp of those mentioned, you CAN do that.
IS it not the same for Windows XP Pro 64 ?
or Vista 64 Pro, or even Windows 7 64
What's the work around? If you have to do a clean install from 32-bit to 64-bit then there is no workaround. Your article title indicates you can upgrade. Anyone can do a clean install.
