I can't reinstall Premium security

[bryche73]

Hi I m having slow performance of my windows 10 so I reset it, I try to reinstall the Premium security via the file in the product subscription email but failed to install it, there is also no error message pop out during the installation. Please advise how to resolve this issue, thanks

1. Download Avast Premium Security: https://files.avast.com/iavs9x/avast_premium_security_setup_offline.exe
2. Follow instructions: https://www.avast.com/uninstall-utility (Run this tool for all prior installed Avast versions..!!)
3. Reinstall Avast with the downloaded installer from point 1.
4. Reboot.
