# Updates

Hydra Agent checks for a new version once a day. When one is available:

1. A notification balloon appears: **Update Available — Hydra Agent vX.Y.Z is available**, with release notes if any.
2. A new **Update to vX.Y.Z** item appears at the top of the tray menu.
3. Click it. A progress window downloads the installer, verifies it, and launches it. The installer closes the running agent, upgrades it and restarts it. Your settings and connected accounts are preserved — updating is not the same as uninstalling.

If you see **Update Verification Failed**, the download did not match what Hydra Vision published. Your current version is untouched — simply try again later, and contact support if it keeps happening.

#### Version no longer supported

Occasionally a very old version can no longer talk to Hydra Vision. If that happens the agent stops syncing and shows a **Version No Longer Supported** message. To continue:

1. Uninstall Hydra Agent via Windows **Settings → Apps → Installed apps**.
2. Download the latest version from the customer portal at [hydravision.ai](https://hydravision.ai).
3. Install it, then enter your API token and connect your terminals again.

{% hint style="warning" %}
Uninstalling removes the agent's settings and logs. After reinstalling you will be asked for your API token and will need to reconnect your MT5 terminals. Your data in Hydra Vision is unaffected.
