Sightline runs on Windows 10 or 11, 64-bit. The installer is named `Sightline__x64-setup.exe`. ## Install Run the installer and follow its steps. It installs Sightline for your Windows user account only, by default in `%LOCALAPPDATA%\Sightline`, so it does not ask for administrator rights. Sightline installs its own updates the same way. Sightline needs the Microsoft Edge WebView2 Runtime, which Windows 11 and most Windows 10 computers already have. If it is missing, the installer downloads and installs it, so keep the computer online during installation. If your computer is managed by a school or district, IT may need to approve or deploy Sightline for you. For a guide written for IT departments, email [support@sightlinebehavior.com](mailto:support@sightlinebehavior.com). ## If Windows says it protected your PC Microsoft Defender SmartScreen can stop an installer it has not seen often, even when the installer is signed. If you see **Windows protected your PC**: 1. Select **More info**. 2. Check that **Publisher** reads **Christopher Ives**. That is the name on Sightline's code-signing certificate. If it shows a different name or **Unknown publisher**, do not run the file; download it again from [sightlinebehavior.com/download](https://sightlinebehavior.com/download). 3. Select **Run anyway**. Your browser may also show a similar warning when the download finishes. In Microsoft Edge, open the download's menu and select **Keep**. If Edge asks again, select **Show more**, then **Keep anyway**. ## If Microsoft Defender quarantines a file If Defender removes a Sightline file, the app may fail to start, or AI or voice features may stop working. 1. Open **Windows Security → Virus & threat protection → Protection history**. 2. Select the entry that names a file in the Sightline install folder (by default `%LOCALAPPDATA%\Sightline`), and check the file name. 3. Select **Actions → Restore**. 4. Restart Sightline. If the file is still missing, run the installer again. On a managed computer, you may not be able to restore the file yourself. Ask your IT department, and email [support@sightlinebehavior.com](mailto:support@sightlinebehavior.com) with the file name and the threat name Defender shows. ## Where your data is stored Sightline keeps its database, its local backups, downloaded AI and voice models, recorded audio, and license files in: ``` %LOCALAPPDATA%\com.sightline.app ``` To open it, paste that path into the File Explorer address bar. This folder stays on this computer. Windows does not copy Local AppData to other computers with a roaming profile, so it is not a backup. To keep a copy somewhere else, use [Back up to a file](/backup-and-restore). Sightline will not save a backup or an **Export records** file inside this folder, and shows "That folder is where Sightline keeps its own records and backups. Choose a different folder." if you try. ## Find the log files Sightline's log files are in the `logs` folder inside the data folder: ``` %LOCALAPPDATA%\com.sightline.app\logs ``` If support asks for logs, attach the files from that folder to your email. ## Uninstall 1. If you will not use Sightline on this computer again, open **Settings → Plan** and select **Deauthorize** first, so your license can be activated on another computer. See [Licensing](/licensing). 2. Open Windows **Settings → Apps → Installed apps** (on Windows 10, **Apps & features**), find **Sightline**, and select **Uninstall**. The publisher listed there is Ethoseen LLC, the company that makes Sightline. 3. In the uninstaller, choose whether to tick **Delete the application data**. It is not ticked by default. 4. Select **Uninstall**. If you leave **Delete the application data** unticked, the uninstaller removes only the app. Your records stay in `%LOCALAPPDATA%\com.sightline.app`, and reinstalling Sightline picks them up again. **Delete the application data** permanently deletes the whole data folder: your database with every student and observation, the backups Sightline kept on this computer (**Automatic backups** and **Back up now**), downloaded AI and voice models, recorded audio, license files, and logs. Save a [backup to a file](/backup-and-restore) in another folder first if you may need these records again. The uninstaller never deletes backups you saved to a folder you chose, or files you exported. Sightline also stores its database key, your license key and, if you paired a phone, the Companion pairing key in Windows Credential Manager. The uninstaller does not remove these, with or without **Delete the application data**. To remove them, open **Credential Manager → Windows Credentials** and remove the entries ending in `com.sightline.app` or `Sightline Companion`. Remove them only after the data folder is gone: without the database key, Sightline cannot open the records in it.
