Format Factory for Windows 8 / 8.1 (Download & Install)
Windows 8 and 8.1 are both past Microsoft's own support cutoff — but the current Format Factory build still officially covers them, with the same 64-bit condition that applies to Windows 7.
32-bit vs. 64-bit on Windows 8/8.1
Windows 8 and 8.1 both shipped in 32-bit and 64-bit editions, and the current 5.22.0.0 build is 64-bit only, a requirement in place since version 5.0.0 (February 2020). If you're on a 32-bit install of Windows 8 or 8.1, the current installer won't run; you need the older v4.10.5.0 release instead.
To check which one you have, open Control Panel → System (or press Win + Pause/Break) and look for “System type” before downloading.
Download Format Factory for Windows 8 / 8.1
~163 MB installer. Requires 64-bit Windows 8 or 8.1 — see above if you're not sure which edition you have.

Install steps on Windows 8 / 8.1
Download FFSetup5.22.0.0.exe from the official link above.
Right-click the installer and choose "Run as administrator" for a smoother install on Windows 8/8.1.
If a User Account Control prompt appears, click "Yes" to continue — standard for any installer, not specific to Format Factory.
Follow the setup wizard's default options and launch the app from the Start screen (Windows 8) or Start menu (Windows 8.1) once it finishes.
Windows 8 vs. Windows 8.1 — does it matter here?
The most visible difference between the two is the interface: Windows 8 launched without a Start button at all, and Windows 8.1 (October 2013) brought it back alongside a boot-to-desktop option. Neither of those interface changes affects Format Factory directly — the app runs as an ordinary desktop program on both, launched from the Start screen tiles on Windows 8 or the Start menu on Windows 8.1. The one thing that does matter across both versions equally is the 32-bit vs. 64-bit split covered above.
Why Format Factory still supports an unsupported OS
Microsoft ended extended support for Windows 8.1 on January 10, 2023 — Windows 8 itself lost mainstream support even earlier, in January 2016. That means neither version receives security patches from Microsoft anymore, regardless of which third-party software you install on top. Format Factory's own compatibility list keeps Windows 8/8.1 in the supported column for the current 5.22.0.0 build, alongside 7, 10, and 11, as long as you're on the 64-bit edition — but that's a statement about this one app, not about the safety of running an unpatched OS in general.
If you're still on Windows 8/8.1 because specific hardware or a specific legacy workflow depends on it, that's a reasonable position — just be more deliberate than usual about where you download software from, since an OS with no further security patches has fewer built-in defenses against a genuinely malicious installer than a currently supported one does.
Common Windows 8 / 8.1 questions
Is there a Windows 8-specific download?
No — one current installer (FFSetup5.22.0.0.exe) covers 64-bit Windows 7, 8, 10, and 11 alike. You don't need a Windows-8-branded build; the same file works across all four as long as you're on the 64-bit edition.
Does it run from the Windows 8 Start screen, or only the desktop?
Format Factory is a classic desktop application — on Windows 8 it appears as a tile on the Start screen that opens the same desktop window as on any other supported Windows version. It was never built as a Windows Store / Metro-style app.
What if my Windows 8/8.1 install is still 32-bit?
Then the current build won't install at all — you'll need the older v4.10.5.0 release instead, which is the last version built for 32-bit Windows. See our old versions page for that download.
Antivirus considerations on an unsupported OS
Windows Defender's definitions still update on Windows 8/8.1 in most cases, but the underlying OS itself no longer receives the security fixes that would close newly discovered vulnerabilities — that gap only grows over time. If you're running third-party antivirus software instead, keep its definitions current before installing anything, this installer included, and read our safety write-up for the specific Defender result we recorded during our own testing on a different Windows version.
The short version for Windows 8 / 8.1
The current 5.22.0.0 build officially supports 64-bit Windows 8 and 8.1 — confirm your edition via Control Panel → System before downloading, since 32-bit installs need the separate legacy v4.10.5.0 installer instead. Beyond that one check, installation follows the same standard steps as any other supported Windows version.
Given that Microsoft no longer patches either OS, downloading only from the official link and keeping your antivirus definitions current matter more here than on a currently supported version of Windows.
Considering an upgrade instead?
If you're on Windows 8/8.1 partly by circumstance rather than choice, Format Factory itself isn't a reason to stay on it — the same installer and feature set carry over cleanly to Windows 10 or 11, so nothing about this specific app should factor into that decision either way.
The practical takeaway
64-bit Windows 8 and 8.1 remain fully supported platforms for the current release — confirm your edition, download from the official link, and the rest of the process is identical to any newer Windows version.
