Teal VPN for Windows: installer codes
The installer (TealVPN-Setup-<version>-amd64.exe or -arm64.exe) reports one of the codes below when it finishes. Run it with /quiet for a silent install; without the switch it shows the same reasons in a window.

What the installer does
- Installs to
C:\Program Files\Teal VPNand adds one entry in Settings → Apps. - Registers the Teal VPN Service, which creates the encrypted tunnel, and the Teal network adapter (Wintun). Both are removed by the uninstaller.
- Needs one administrator prompt. Never needs a restart. Installs offline: it downloads nothing.
Uninstall
Settings → Apps → Teal VPN → Uninstall. Silent: "C:\Program Files\Teal VPN\Uninstall Teal VPN.exe" /uninstall /quiet. It removes the service, the adapter and its driver, the firewall rules, the update task and all program data.
