Happ on Windows: Install and Connect with a Key
Happ for Windows is a desktop program built on the Xray-core engine that needs an access key from the Telegram bot to reach a server. Let's walk through setup step by step.
Step 1. Download the installer
Open the Windows download page and grab the installer file. Run it once downloaded and complete the standard setup on your computer.
Step 2. Request a key from the Telegram bot
Open the service's Telegram bot and get an access key or subscription link. Copy it right away — you'll need it as soon as you launch the app on your computer for the first time.
Step 3. Paste the key into the app
Open Happ on Windows, go to the add-subscription section, and paste the link from your clipboard. The app processes it automatically and builds a new connection profile with a list of available servers.
Step 4. Pick a server and turn the VPN on
Once the subscription is added, select a server from the list — usually the closest one geographically for the lowest latency. Click connect: on first launch, Windows may show a system prompt to install a VPN driver, which needs your approval.
Options for advanced users
The Windows app also unlocks finer controls, such as split tunneling — where part of the traffic bypasses the VPN and goes out directly — plus support for adding your own custom configurations.
Frequently asked questions
Do I need administrator rights to install Happ on Windows?
Yes, on first connection the system will ask for administrator approval in order to install the VPN driver.
The key won't paste into the app — what now?
Check that the link was copied in full with no stray spaces, then try pasting it again in the add-subscription section.
Is there a free way to use Happ on Windows?
Yes, a 3-day trial is available through the Telegram bot before you need to commit to a paid plan.
How many devices can connect at once on Windows?
The number of simultaneous connections depends on your plan; an extra device can be added on the pricing page if needed.
