    In my opinion, new/clean installation is better than reinstallation.

    Kindly perform below steps & see if this helps you in anyway.

    1) Uninstall the bitdefender product with add/ remove programs option in windows

    2) To remove the remaining files download and run Bitdefender product uninstaller (

    3) Restart PC in safe mode (

    4) As soon as desktop opens, assuming your windows drive is C, open below things in run (windows icon + R) command 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)

    5) 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

    6) Open registry editor through run command (windows icon + R) and then type regedit. Once registry editor opens, click on edit -> find, make sure to tick mark match whole strings only. Type bitdefender in search box and click find next. If any file or folder under name of bitdefender is found, delete it. Continue searching the registry and deleting until the search will report no registry keys found.

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

    8) Remove devices from online bitdefender central (

    9) Download online installer for your respective bitdefender product from below stated links

    Hi @Tajul

    Try running a repair, and see if that will resolve it for you. It's not a complete uninstall, and you may lose a setting or two that you had made (may go back to default), but it's worth a try.

    Hello @Tajul,

    This situation can also be caused by a temporary internet connectivity issue. Bitdefender updates as soon as it manages to successfully download the update files. If this is not the case, the repair instructions provided by Scott above should do the trick.

    Let us know how it goes.
