Can't Reinstall Bitdefender

When I tried to reinstall BD AV Free Ed., the installation did not complete and I was prompted to use the Uninstall Tool. But the Uninstall Tool finished with errors. I'm running Windows 10 64 bit

    Okay, so we need to go into safe mode now, to solve this issue.

    1) Uninstall bitdefender agent and bitdefender free antivirus

    2) Restart pc in safe mode (

    3) As soon as desktop opens, assuming your windows drive is C, open below things in run command (windows icon + r) one by one :

    C:\Program Files (delete any folder with name bitdefender)

    C:\Program Files (x86) (delete any folder with name bitdefender)

    C:\ProgramData (delete any folder with name bitdefender)

    C:\Users\{your pc name}\AppData\Local (delete any folder with name bitdefender)

    4) Open run command again and run below command one by one :

    temp ,delete all the files in the folder

    %temp% ,delete all the files in folder

    prefetch ,delete all the files in folder

    5) Restart your pc in general mode by unticking the option that you selected to run the system in safe mode and then click apply.

    6) Try reinstalling bitdefender free

    Keep posted.

    @Flexx, thank you for your response. I was able to complete steps 1 - 5, but I got the following error when I tried reinstalling.

    It might be worth mentioning that there's a BD registry key that I can't delete.

    This might be due to following things.

    1) Are you running the installer in safe mode. If so revert back to general mode for installer.

    2) If you are running in general mode, go to C:\Windows\temp , if there is no such folder, create one and then try to install bitdefender free again.

    If nothing happens, kindly drop an email to bitdefender support at [email protected] describing your issue in brief with the steps you have taken to resolve the issue till now.



  • I ran the installer in general mode and I found the folder. I got the same error again and will send an email.

  • These instructions don't work.
