How to install a third year of BitDefender


I have used BitDefender happily for the last two years. I am now seeking to renew for a third year. I have purchased a renewal package (essentially a new Activation Code). I have logged in to '' and followed the download instructions.

I have downloaded a file named 'bitdefender_windows_7d9f5a26-4dcd-4526-acb0-1d75bbd5bf71.exe'. It is some 16MB in size, which is consistent with previous years.
When I click on that to execute I get the usual UAC message, and click 'YES'. Nothing further happens.

In the UAC notice It says: Program location: "C:\Users\tim\AppData\Local\Temp\RarSFX4\bddeploy.exe".

But I do not have a sub-directory 'RarSFX4'. I DO have 'RarSFX3', and it does contain a file 'bddeploy.exe', with a creation date of today (2nd June 2024). If I double click that I get the UAC message, but nothing further.

What should I try next, please?

    You don't need to install the app again if you already have it installed, you just need to purchase an additional year of subscription using the same Bitdefender account - this way the subscription is updated automatically without the need to reinstall the app.

    Thank you. I followed the installation instructions more carefully and it worked.
