Fixing Service Mode Installation Failures

Service mode is TUN's prerequisite — a system service that performs the privileged work on the app's behalf. If it won't install, the TUN switch stays grey. Failures come down to three causes: permissions, leftovers, or interference.

Fix sequence (try in order)

1. Reinstall as administrator

1. Fully quit Clash Verge (tray icon → Quit);
2. Right-click the app icon → Run as administrator;
3. Settings → Service Mode: uninstall, then install. This alone resolves most cases.

2. Purge a half-dead service entry

A broken previous install can block every reinstall attempt. In an elevated PowerShell:

sc.exe stop clash_verge_service
sc.exe delete clash_verge_service

Then install again from inside the app.

3. Check the antivirus

"A program registering a system service" is exactly what security suites watch for. Check your AV's blocked-actions log, add the Clash Verge install folder to exclusions, retry. Real-time protection modules are the usual culprits.

4. Avoid non-ASCII install paths

Install paths containing non-Latin characters occasionally break service registration. Reinstalling to the default path rules this out.

Verify

sc.exe query clash_verge_service

RUNNING means healthy — the TUN switch should now respond. If not, grab the exact error from the Logs page and match it against the error reference.
