Bitdefender Free Antivirus installation failed multiple times despite extensive troubleshooting


I have tried installing Bitdefender Free Antivirus four times on two of my computers, but every time, the installation ended with an error. (It also makes me re-download it every time that I retry). Bitdefender Free antivirus would have been my first choice, but I am not able to get it to install. I tried every troubleshooting step at without success. I could just use Windows 10 default antivirus, but I would much rather use Bitdefender Free Antivirus. I could try again and post a screenshot or if there's a log file saved somewhere about it's installation attempt, I would be happy to attach that if necessary or requested. Thanks for any help that you can provide.
