After installing, open the app. A window will ask for your license key. Paste the key you received on WhatsApp or email after purchase, then click Activate. The app will verify your key online and unlock all features. License is tied to your account and works on one PC at a time.

When a new version is released, we send a WhatsApp notification with the download link. Simply download the new installer from the download page, run it, and it will update over your existing installation. Your settings and data are preserved.

Each license is valid for one machine at a time. If you want to switch computers, contact support via WhatsApp — we can transfer the license for you. Simultaneous use on multiple PCs with one license is not allowed.

Zerodha API tokens expire daily around 6:00 AM IST. You need to re-login through the app's Broker panel each trading day. The app will prompt you if the token is missing or expired. Full guide is in the "Broker Login & API" section above.

Try these steps in order: (1) Close unused tool windows, (2) Restart the app, (3) Check your internet speed, (4) Ensure you have at least 4 GB free RAM, (5) Update to the latest version. If the issue persists, contact support with your system specs.
