Hi @JAEMYOUNG KIM ,

Open ‘hosts’ system file by note app, add visual studio download IP.

Do you mean you have tried the suggestions from this thread: visual studio download very slow but it didn’t work?

If so, please try following:

1. Run CMD as administrator, run DISM.exe /Online /Cleanup-image /Restorehealth. Wait for the command finishes running, run sfc /scannow command. These two commands help to fix the missing and corrupted system files. After that try to reinstall VS.
2. Try to update Windows OS, make sure that all the patches have been installed and there’s no Windows Update error.
3. Check the 3rd-party programs like antivirus, network proxy, security management software, make sure that they didn’t block VS from connecting to the network and downloading files.
4. Navigate to C:\Windows\Microsoft.NET\Framework\v4.0.xxxxx\Config\ folder, find the machine.config file and the machine.config.default file. Make a backup of the machine.config file, then replace the content in machine.config with the content in machine.config.default file. Reinstall VS.
5. Try to run VS setup file as administrator.

Feel free to let us know the results.

Best regards,

Tianyu
