AFTER DOWNLOAD
Installation and first-time setup after download
The package only deploys the client. Importing subscriptions, choosing a routing mode, and configuring the system proxy still need to be completed after first launch.
STEP 01
Exit the old process
Before upgrading, exit normally from the client menu and check that the tray icon disappears. On Windows and Linux desktops, closing the window does not always end the background process. If the installer reports a file lock, use Task Manager or the system monitor to confirm that the relevant process has stopped before continuing.
STEP 02
Record key configuration
At minimum, keep the subscription URL, active configuration, routing mode, DNS rules, per-app proxy scope, and local listening ports. Exported configuration may contain device-specific paths and should not be copied wholesale to another system. For manual rules, record their order as well, since match order in the array affects traffic routing.
STEP 03
Complete installation and permissions
Open the package using the operating system's standard installation process. The first time a mobile client starts the VPN service, the system displays a connection confirmation; enabling the system proxy on desktop may also require a security prompt or desktop-session permission. Confirm only the explicit items shown by the current system, and do not apply steps from another platform.
STEP 04
Import and verify configuration
After importing a subscription, update it manually once and confirm that groups and nodes appear correctly. Then choose the routing mode and active configuration. After connecting, check the client log for address, port, DNS, or certificate errors. If system apps still cannot connect as expected, verify the system proxy and routing rules instead of repeatedly reinstalling the client.
