Download KuaiLian VPN for Windows from the Windows section on the download page. Avoid portable builds, cracked installers, and repackaged downloads because they are difficult to verify and may behave differently from the current client.
Before Running the Installer
- Confirm that your Windows version is supported.
- Use the current source indicated on the download page.
- Make sure you have administrator permission.
- Close other VPN, proxy, or acceleration tools before testing.
Install on Windows
Download the installer
Open the Windows download section and save the current installer. If the browser reports that the download was interrupted, delete the file and download again.
Run with administrator permission
Right-click the installer and choose Run as administrator. VPN clients often need to install network components, and a regular user account may fail silently or halfway through.
Handle SmartScreen carefully
Windows SmartScreen may warn about software downloaded outside the Microsoft Store. Check the source and decide whether to continue. If security software blocks the app, add a temporary allow rule instead of leaving protection disabled.
If the App Opens but Will Not Connect
Read the connection troubleshooting guide. If the app itself will not open, restart Windows, remove the old version, and reinstall after checking the current download page.
