Installed on Win11 but no window? Click Show hidden icons at the lower-right of the taskbar. Find the client, then drag it onto the visible tray so you are not hunting the chevron next time.
Win10 users expect a desktop shortcut. Win11 creates fewer shortcuts, so a flash looks like a crash. If Task Manager already lists the process, setup succeeded.
Pin the icon in Settings
Settings → Personalization → Taskbar → Other system tray icons, turn the client on. If that row is missing, dragging from overflow still works.
Cannot connect: switch nodes before reinstall
A visible window means the PC client is ready. Protocol and nearby nodes: guide. Reinstall will not punch UDP through a company firewall.
SmartScreen: installer does nothing. Package: Download.
FAQ
Does Kuailian support Win11?
Yes. Take the Windows card on this download page. No extra Win11-only package.
Start search finds nothing?
Search the product name from setup. If still missing, confirm the exe finished — do not only unzip to the desktop.
Tray icon will not open?
Single left-click. If a process exists in Task Manager with no UI, end it and launch from Start. Then check the firewall.
Need the installer or platform notes?
