Hello! How do you do sir? I wanted to try using Bitdefender antivirus free edition. But during the installation I faced some issues. When the installation was close to 90% it performs a rollback action due to installation error. And after that it says Error: Installer initialization failed or something. Before installing bitdefender I have already deleted other antvirus software and even manually checked and deleted the remaining folders. Can you plzz help solving this problem? Thank you.
