How to install Bitdefender on Windows

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.

Hello @MikeA ,

Did you get a error message or code? If not mind sending a screenshot or a video of what is going on?

How to Screenshot in Windows: Windows Key + "Print Screen" key (PRT SCN)

I have the same issue as Dustey. I download the install package and when it's executed it shows up as a process, in task manager, as well as another process 'bddeploy.exe. They run for about a minute and then disappear. Never actually launches the installer. 😫

Any assistance in sorting this matter out would be greatly appreciated.

Ich habe zwei Notebooks mit WIN 10 und möchte beide mit BitDefender ausstatten und bald ein drittes Notebook auch mit BitDefender zum Leben bringen. Das hauptthema für mich ist das MS-Konto so auszustatten das alle drei gut zusammen leben und alle drei gleich gesteuert und geholfen werden und tragen den gleichen Schlüssel.Ist es machbar und sinvoll?

Thanks for this video. I was wanted to use bitdefender free version in my pc. As I want to check is that perfectly work on my pc. After that I will make decision to install the paid version.

Can someone let me know if there's WordPress plugin, I want to use this functionality for my website.

Other people have commented and I too have the same issue. Support center does not help. A waste of money.

So I downloaded the installation setup, once I open in it. Nothing happens. Not even an error message.

Hello @Esbaratao,

Could you please write in English and tell us what error message you have encountered during activation? Also, please specify if the purchase was made at the official Bitdefender Amazon store, as not all marketplace sellers are affiliated with Bitdefender.

Thank you.

@k70 are you getting any sort of error message? Does the stub installer download, then an error when Bitdefender tries to download the security software, or in running the setup?

@k70 if you've previously had Bitdefender installed on those devices, I would suggest running the Uninstaller to make sure any previous remnants are deleted. Delete any of the previous BD installers. Empty the Recycle bin.

Then do the restart. Confirm all the BD files are deleted (I've had some left in Windows 11 before) in Program files, Hidden files Users/ App Data/ Local and Roaming. Empty the recycle bin.

Then go into Safe Boot (msconfig) but first, if you have any Pro version of Windows installed, disable Bitlocker, otherwise you would need your key to get back to your normal Windows desktop.

Delete %temp% files and Prefect by right-clicking the start button and Run, and typing in those commands in the Run box. Then right-click the start button and Run, then type msconfig to load and disable safe boot. Restart your device.

Now, try going back into your Central account and "Install protection on a new device/on this device," your version of BD, and see if it installs for you.

Let us know your results.

@k70 Thank you for posting back the steps that worked for you. Indeed, on a high-profile thread like this one, it could absolutely help someone in the future.

Cheers, and have a great weekend :)

@k70 my question is that can bitdefender detect extension virus, mean that virus which has authority to change the extension into some awkward extension that file become unaccessible...

Hi Lucyoscar,

thank you for trying to help me, I am a bit to old to understand all this and can not understand why Bitdefender is so complicated to install. My older security expires tomorrow and I hope my new order will follow automatically if not I guess I am a bit in trouble. Thanks again for trying to help me. Regards

yes, both my devices are on my latest Bitdefender purchase, however I still have one VPN which will expire in April 2023. Do I still need this or should I erase that VPN?

Also I get constant reminders that my iPhone is compromised, do I really need to use my Finger print or a passcode to avoid that?

Sorry, why can't I submit a new post? I explained the issue I am having, but I am getting blocked by Cloudflare after clicking 'Post Comment'. What could I be doing wrong?

I am having difficulties in getting Bitdefender Premium Security working on my computer using Windows 11.

I seem unable to get the download to work. I currently have Bitdefender Total Security should this be deleted first.

I am not particularly good with a PC so if you could point me towards a simple set of instructions I would be grateful. This new software seems very complicated to install.. Please help me

Hello @tonyevans

Your previous Total Security license is still valid until 2023/06/18 and you have also activated the Premium Security subscription in your Central account and this is valid until 2024/03/28.

The Central account can accommodate multiple subscriptions with the scope to protect more devices and the two licenses will overlap until 2023/06/18 when the previous license expires. I have noticed that your devices are still protected by the Total Security license, thus if you wish to move them to Premium Security, you can reallocate them manually by following the instructions from the article below:

But the issue with overlapping is that you will lose aproximately 2 months validity either way. If you move the devices from Total Security, the license will run "empty" until its expiration, because it will no longer protect any devices. If you don't move the devices, Premium Security is already active and this means that it will run for two months without covering any devices. However, you will still be able to make good use of the included Password Manager and the Premium VPN from this package.

In this scenario, I would advise the following: you can contact the Support teams and inform them you have upgraded your protection to the Premium Security suite, but you still have some validity left on the previous license (TS) and this could not be cumulated automatically during the activation of Premium Security, because the licenses are not identical. So, you can ask our representatives to remove the Total Security license from your Central account completely, and add its remaining validity to Premium Security. This way, no validity will be lost.

Hello @Teddi,

I think that the error you receive - The app you are trying to install isn't a Microsoft- verified app comes up because your Windows is running in S mode. Windows in S mode is designed for security and performance, exclusively running apps from the Microsoft Store. If you want to install an app that isn't available in the Microsoft Store, you'll need to switch out of S mode. Switching out of S mode is one-way. If you make the switch, you won't be able to go back to Windows in S mode. There's no charge to switch out of S mode. Follow the steps below and try to install Bitdefender afterwards:

Let us know how it goes and if this was the actual reason behind the installation issue.

Regards,

Alex
