Installing

Aveno runs on 64-bit Windows 10 and Windows 11.

1. Download the installer from the home page.
2. Run it. It installs for your user account and creates Start Menu and desktop shortcuts.
3. Launch Aveno. It does not run as administrator, and it does not need to.

Verifying your download

Every published installer has a SHA-256 fingerprint, shown on the home page and served with the download itself in the X-Checksum-SHA256 header. To confirm your copy matches, open PowerShell in your Downloads folder and run:

Get-FileHash -Algorithm SHA256 .\"Aveno Setup.exe"

The Hash it prints should equal the value on the home page, ignoring upper/lower case. If it does not match, delete the file and download it again.

Activating Premium

Open Aveno and enter your licence key on the activation screen. Keys look like AURA-XXXXX-XXXXX-XXXXX.

1. The key is redeemed once, online, and gets bound to that machine.
2. The server returns a signed licence which Aveno stores locally.
3. From then on it is verified offline, on your machine, every launch — no internet needed.

Because a key binds to one machine, redeeming the same key on a second computer is refused. If you have changed hardware, get in touch and the key can be reissued.

How updates work

Aveno checks for a newer version when it starts. If one exists, an Update ready panel appears in the sidebar; clicking it downloads and runs the new installer.

Before anything is executed, the downloaded file has to pass four independent checks:

1. Integrity — its SHA-256 must equal the hash published in the release manifest.
2. Unpredictable location — it is written to a randomly named temporary path that must not already exist.
3. Authenticity — it must carry a valid Authenticode signature chaining to a trusted root.
4. Freshness — its embedded version must not be older than the version already installed.

If any check fails the file is deleted and the update is abandoned. Aveno will never run an installer it could not verify, which is also why it cannot be tricked into downgrading you to an older, weaker build.

Why it asks for administrator

The main application runs with your normal user rights. A few operations genuinely need administrator — optimising a drive, clearing the Windows Update cache, resetting the network stack, running System File Checker, removing a machine-wide startup entry.

When you trigger one of those, Aveno launches a short-lived helper process just for that single operation, which is what produces the UAC prompt. The rest of the app — the interface, the network code, the scanner — never runs elevated.

Uninstalling

Use Settings → Apps → Installed apps in Windows, or the Uninstall Aveno shortcut in the Start Menu folder. Both remove the program files, the shortcuts, and the uninstall entry.

Your settings and licence live in the registry under HKCU\Software\AuraCleaner and are left in place, so reinstalling keeps your activation. Delete that key if you want a completely clean slate.
