Desktop app updates

The Windows app checks for a new version a minute after it starts and every 30 minutes after that, downloads it in the background, and shows a Restart to update button. Your work is saved before it restarts. After seven days the update becomes required. Microsoft Store installs are updated by the Store.

How updates arrive

  1. A minute after Athanor starts, and every 30 minutes after that, it asks whether a new version is out.
  2. If one is, it downloads in the background while you keep working.
  3. A blue Restart to update button appears in the top bar. Hover it to read "Athanor {version} is ready. Your work is saved first, then the app restarts."
  4. Press it when it suits you. Athanor saves every open document, installs the new version and opens again.

If you leave Athanor idle for 30 minutes with an update ready, it installs the update by itself, saving first in the same way.

After an update, the What's new card lists what changed. The full list for every version is on the release notes page.

Note

The web app updates differently: a new version installs behind the page and a notice offers Reload. If you ignore it, the new version starts the next time you open Athanor.

When an update becomes required

An update you have not installed stays optional for seven days after it was published. The button says how long is left, for example "Required in 3 days."

After that, Athanor shows a card titled Time to update Athanor that reads "Version {version} has been ready for more than 7 days, and this one is no longer supported." Its one button, Update and restart, saves your work and installs it. Some versions are marked as required from the start, and the card then reads "Version {version} is a required update."

Microsoft Store installs

If you installed Athanor from the Microsoft Store, the Store updates it, not Athanor's own updater. The app still checks the Store, downloads in the background when Windows allows it, and shows the same Restart to update button. A version the Store marks as mandatory is required at once.

The direct download (Athanor-setup.exe) and the Store version are the same program. Do not install both: pick one and uninstall the other from Windows Settings › Apps.

No update is showing

  • Wait a minute after starting. The first check runs one minute after launch.
  • Check your connection. If the update server or the Store cannot be reached, Athanor simply asks again at the next check. Nothing is shown in the meantime.
  • Compare versions. Help › About Athanor shows the version you have. The newest is at the top of the release notes.
  • Your organization may manage updates. On a work or school computer, IT can turn the built-in updater off with a policy file (autoUpdate: false in %ProgramData%\arbastro\Athanor\policy.json). Updates then come from IT, so ask them.
  • Reinstall over the top. Download the installer again from the download page and run it. Your documents are kept: they live in your account and on this device, not in the program folder.

If none of these helps, report the problem with the version from Help › About Athanor.
