Older versions and full notes: release notes.

Windows 10 or Windows 11, 64-bit
An ordinary office PC or laptop
Internet only to download, start the trial or activate, for a short licence check now and then, and for updates. Day-to-day work is fully offline.
A PDF reader to open payslips. Outlook (or another e-mail program) if you want the app to prepare payslip e-mails.

Download AntAIPayroll_Setup.exe from this page.
Double-click the file and follow the steps.
Windows SmartScreen may show "Windows protected your PC". This happens because the installer is not code-signed yet. Click More info, then Run anyway, but only if you downloaded the file from this site and, ideally, checked its SHA-256 (below).
Open AntAI Payroll. The first-run wizard helps you choose a data folder, create your company and set a password.
Write down the recovery key on paper. Then start your free trial.

A SHA-256 check confirms the file is exactly the one we published and was not changed on the way.

Open the folder where the file was saved, usually Downloads.
Hold Shift, right-click an empty space in the folder and choose Open PowerShell window here (or Open in Terminal).

Type this and press Enter:

Get-FileHash .\AntAIPayroll_Setup.exe -Algorithm SHA256

Compare the Hash it shows with the SHA-256 on this page. Upper or lower case does not matter. If they are different, do not run the file. Download it again and tell us.

The app checks for updates when it starts. You can also check any time in Settings > Updates.
It downloads the new installer, checks its SHA-256 and signature, and takes a backup before installing.
Installing a new version over the old one keeps all your data, your licence and your settings.
You can also update by hand: download the latest installer from this page and run it.
