Daedalus 11.6.2 Fixes Windows Update Installation

Input Output released Daedalus 11.6.2 with two fixes to the wallet’s built-in updater. The Windows fix addresses an issue that could leave users on their existing version after they chose to close Daedalus and install an update. A separate change lets the wallet reuse an installer it has already downloaded and verified.

The Windows installer stays running after Daedalus closes

Daedalus runs its own Cardano node and verifies the blockchain locally. When a user starts an update on Windows, a background supervisor shuts down the node and wallet services before launching the installer with administrator privileges.

The installer previously joined the same Windows process group as the supervisor. That group was configured to close its remaining processes when the supervisor exited, so Windows also stopped the installer before it could finish. Version 11.6.2 removes that shutdown rule once the installer has started successfully. If the user declines the Windows administrator prompt, the rule stays in place.

Daedalus checks for an installer before downloading again

The updater now looks in its download folder for a copy of the installer before requesting a new one. If a copy is present, Daedalus calculates its SHA-256 checksum and compares it with the value in the official update feed. A match lets the wallet offer installation immediately using the existing file.

If the checksum differs, or if Daedalus cannot complete the file check, the updater downloads a fresh copy. The checksum verification performed at installation remains in place.

[NEWSBREAK]

A feed failure no longer clears the downloaded file

The release also changes how Daedalus handles a saved installer when it cannot retrieve or verify the update feed. A failed check previously could cause the wallet to remove the file. Version 11.6.2 keeps the installer and its local record in place so the updater can check the file again once the feed is available.

Daedalus clears the saved installer when it successfully retrieves and verifies the feed and finds that the feed no longer lists an update for that platform.
