Why won't Bitdefender install?
Since the last major patch (the Windows update), it runs smoothly without any issues.
Are there additional antivirus programs or older versions of Bitdefender already set up on your computer? Occasionally, the system restricts more than one third-party antivirus at once. You might also attempt to turn off Windows Defender or allow the Bitdefender installer to run.
