Hello, sometimes this problem happens when Windows or the Microsoft Store is not fully updated. You can try these steps:
- Make sure Windows Update is complete.
- Open the Microsoft Store → click on Library → select Get updates.
- Restart your laptop and try again.
- If it still doesn’t work, uninstall “App Installer” from Microsoft Store and install it again.
- You can also try downloading WhatsApp directly from the official website: whatsapp.com/download.
I hope this helps you. Even if it doesn’t fully solve the issue, it gives a safe way to move forward.
