Windows only. The app is a desktop application, not a service — nothing runs unless you open it.
SHA-256:
Some modules need more than the base app. Anything not listed here is bundled.
| Component | Requirement |
|---|---|
| Operating system | Windows 10 or 11, 64-bit |
| Runtime | .NET 9 Desktop Runtime (x64) — download from Microsoft |
| Xbox / Epic / Ubisoft | An account for the service you're working with, and an internet connection |
| Steam modules | Steam installed and signed in |
| GFWL module | Nothing extra — the x86 injector ships with the app |
| Xbox 360 module | Your profile package (CON/LIVE/PIRS) copied to the PC |
| Disk space | Roughly 500 MB, mostly title data and backups |
Five minutes, most of it waiting on the .NET installer.
Grab the x64 Desktop Runtime (not the SDK, not the ASP.NET one) from Microsoft's download page. If you skip this, the app won't start and Windows will show a runtime error instead of anything useful.
Unzip the release somewhere you own — a folder under your user directory or a second
drive is ideal. Avoid Program Files: the app writes backups and title data
next to itself, and that directory needs admin rights for every write.
In PowerShell, compare this against the SHA-256 published above:
Get-FileHash .\UltimateAchievementsLab.zip -Algorithm SHA256
Windows marks anything downloaded from the internet as blocked, which makes the injector fail in ways that look like bugs. Clear it on the extracted folder:
Get-ChildItem -Recurse .\UltimateAchievementsLab | Unblock-File
The GFWL module injects into a running process and the Steam tools read and write game memory. Heuristic scanners flag that pattern regardless of intent, so a warning here is expected rather than a sign something is wrong. Add an exclusion for the folder you extracted to if your scanner quarantines it.
Launch UltimateAchievementsLab.exe. No installer, no service, no startup
entry. Sign in to whichever platform you want to work with from the app's settings, and
it'll pull your title list from there.
Delete the folder. Nothing is written to the registry or to
Program Files; per-user data lives in your Documents folder and can go with
it.
Editing achievement and stat data carries risk on any live service — up to and including action against your account by the platform holder. That risk is real and it is yours to take.
Use a throwaway account if the account matters to you, keep the backups the app writes before it edits anything, and read the notes for your platform's module in the Discord before your first run.
Each platform module has its own support channel on the Discord, plus a forum for bug reports. Include your app version, the game, and what you expected to happen.
