Hello Tuvshinbayar Tuvshuu0330,
Thank you for posting in Q&A forum.
Error code 0x800704CF typically indicates a network-related problem.
Let's try a few steps to troubleshoot this:
- Ensure that your computer is connected to the internet. You can try opening a web browser and visiting a website to confirm that your internet connection is working.
- If you're using a VPN or proxy, try disabling it temporarily to see if it resolves the issue. Sometimes, these services can interfere with the activation process.
- Make sure that your firewall is not blocking the activation server. You can temporarily disable the firewall to see if it helps. Go to Control Panel > System and Security > Windows Firewall > Turn Windows Firewall on or off.
- Windows has a built-in troubleshooter that can help diagnose and fix activation issues. Go to Settings > Update & Security > Activation and click on "Troubleshoot."
- Sometimes, incorrect DNS settings can cause activation issues. You can try changing your DNS settings to use a public DNS server like Google's (8.8.8.8 and 8.8.4.4). Go to Control Panel > Network and Sharing Center > Change adapter settings, right-click on your network connection, select Properties, and then select Internet Protocol Version 4 (TCP/IPv4). Click on Properties and enter the DNS server addresses.
I hope the information above is helpful.
If you have any questions or concerns, please feel free to let us know.
Best Regards,
