On Windows, SmartScreen, admin prompts, AV quarantine, and the first firewall dialog block installs more often than “not knowing Next.” With a trusted package, handle them in order—don’t shop five mirror sites.
Use the download center. Context: safe or virus; install by OS.
Which blocker are you hitting?
| What you see | Likely blocker | Do this first |
|---|---|---|
| “Windows protected your PC” before setup runs | SmartScreen | Verify publisher, then “Run anyway” |
| Setup asks for admin mid-install | Service or Tun elevation | Portable install + system proxy first (Tun start failed) |
| App file vanishes after download | AV quarantine | Restore and exclude the install dir |
| First launch shows no connections | Firewall prompt missed | Allow on private networks (firewall) |
SmartScreen
More info → Run anyway after the filename/publisher matches the release notes. If they don’t match, stop.
Administrator rights
Service mode / Tun usually needs elevation (Tun start failed). No rights at work: portable install + system proxy first.
AV and firewall prompts
Restore quarantined files and exclude the install dir—skip “undetected” repacks. Allow on private networks; deeper issues: firewall.
Three checks after install
- App starts; version matches.
- Subscription updates with nodes (setup).
- System proxy shows hits; Tun later if needed (Tun & AI, getting started).
Stop
Unknown mirrors raise fake-installer risk. Ports: ports.
