solution to help (Reinstalling Bitdefender VPN software)

1. Close the main Bitdefender VPN window

2. On the taskbar, right-click the "Bitdefender VPN" icon -> click "exit"

3. Uninstall the "Bitdefender VPN" program (you can uninstall "Revo Uninstaller Pro" cleans up various leftovers) or (Win + R icon) insert "appwiz.cpl" (without quotes)

remove "Bitdefender VPN"

4. Restart your computer in safe mode (this is in order to delete the remnants of the "Bitdefender VPN" folders), it may not be very important.

in safe mode delete folders named Bitdefender VPN, do as follows

1. When the desktop opens, provided that your Windows drive is C, set the following commands in Run mode (Win + R icon) in turn:

C: \ Program Files \ bitdefender (delete the folder named bitdefender vpn)

C: \ ProgramData (delete the folder named bitdefender vpn)

C: \ Users \ {your computer name} \ AppData \ Local (delete the folder named bitdefender vpn)

2. Set the command to execute again (Win + R icon) and make the following commands below:

temp, delete all files in the folder

% temp%, delete all files in the folder

prefetch, delete all files in the folder

3. Restart your computer normally, unchecking the option you selected to start the system in Safe Mode, and then click Apply.

4. Open the main window of the "Bitdefender" antivirus -> protection -> firewall -> settings -> default application behavior -> change the default rules -> allow -> OK (this is to prevent the firewall from asking permission questions)

5. Open the main window of the "Bitdefender" antivirus -> privacy -> install VPN

note that the folders "AppData" and "ProgramData" are hidden

Enjoy your work.

Sorry for my (translated) English.

If it can be helpful, I had a similar error (code: 9) and couldn't resolve with the proposed solutions.

Instead I solved it by going to this \ Program Files \ Bitdefender \ Bitdefender VPN \ installer folder and clicked installer.exe and it worked.

Regarding VPN Error 12 -- Having read the previous comments, applying the KISS system (as I may have to talk a user through this over the phone one day), I tried the following with unfettered success:

• Right-click the Bitdefender VPN icon and select Exit to close the program.
• Right-click the 'Start button', select Apps and Features.
• Select Bitdefender VPN and click Uninstall to remove from the system.
• After the uninstall is complete, open the File Explorer and select This PC from the navigation pane.
• Right-click on the drive and select Properties. In the pop-up window select Disk Cleanup.
• Select Clean up system files. Make sure the Temporary files checkbox is ticked. Click Okay to start the file cleanup.
• When this is done navigate to the ~\Program Files\Bitdefender\folder and delete the folder Bitdefender VPN.
• Restart the computer.
• When finished initializing, open the Bitdefender Antivirus Dashboard and Install Bitdefender VPN from there.

I had no issues whatsoever following this method, and might even be able to talk by In-laws through this in a pinch.

Enjoy your day.

Just tried the above solution for Error 12,

Followed it to the word and now, Error 9.

I had no problems yesterday (15 Nov 21) and now today cannot connect. No updates on Windows, nothing.

What is going on ???
