Hi,
As Nikorr and other members in this thread have stated, you cannot simply downgrade from Windows 7 64-bit to Windows 7 32-bit. When migrating from Windows 7 32-bit to Windows 7 64-bit, or vice versa in your case, it is important to note that a clean or “custom” installation will be required. For more information, see
Installing and reinstalling Windows.
Also, as several members within the thread have pointed out, in most cases, applications that work within Windows 7 32-bit will also function just the same in Windows 7 64-bit. It is important to assess what architecture you will need. When considering Windows 7 32-bit or 64-bit you may find the following FAQ
32-bit and 64-bit Windows helpful. As another resource, Microsoft has provided a
video outlining 32-bit and 64-bit Windows 7.
Should you encounter an application that requires a 32-bit operating system, typically those applications are known as legacy applications and will not work in either architecture of Windows 7 (32-bit or 64-bit). In this case,
Windows XP Mode and Virtual PC are usually recommended tools as Windows XP Mode is a virtualized environment of Windows XP Professional 32-bit which runs directly from your Windows 7 desktop. Windows XP Mode and Windows Virtual PC are available on Windows 7 Professional, Windows 7 Enterprise and Windows 7 Ultimate. For those who are not currently running Windows 7 Professional, Windows 7 Enterprise, or Windows 7 Ultimate, there is an easy upgrade path to Windows 7 Professional or Windows 7 Ultimate through the
Windows Anytime Upgrade program.
Please note, Windows XP Mode is a virtualized environment and is not recommended for graphically intense applications however, for most legacy applications it will work just fine.
