In case our client is not able to install virtual Ethernet adapters that are required for it to work properly, there’s a big chance that it is caused by the driver signing check for Windows. On some systems, it is not allowed by Windows to install drivers that are not signed by the Microsoft. Along with millions of other drivers, the TAP-Adapter drivers of our software are not signed.

However, this has nothing to do with the driver’s security. It is just that the driver developer didn’t certify the driver by Microsoft. Below we have given 5 different methods to deactive the driver signing check. You can try all of them or begin with method 4, which may very well work with your Windows version.

If you are Windows XP user, you’ll need to use method 5.

Once done, uninstall our software, restart your PC and reinstall the software. Please note that in order to prevent issues due to insufficient privileges, the PureVPN client should be reinstalled by right clicking on the PureVPN setup file and choosing ‘Run as Administrator”, as well as launching the client this way.

Method 1: Type cmd.exe in the Search Bar from the Start Menu and hit Enter. Be sure that you are logged on as Administrator.

Type the following and hit Enter:

bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS

bcdedit.exe -set TESTSIGNING ON

Method 2:This feature can be controlled by a group policy.

Navigate to Run from the Start Menu and type GPEdit.msc. Now head to the User Configuration> Administrative Templates -> System -> Driver Installation -> Code signing for drivers and click on ‘Disabled’ and click OK.

Method 3: In case you are unable to access it, change it via Registry by following these steps:

Go to Start> Run> regedit.exe

Search for: [HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows NT\Driver Signing]

No change the BehaviorOnFailedVerify key value to “0” and reboot.

Method 4: Press F8 repeatedly while the system is in the booting process. You will see a menu where you have to select “Disable Driver Signature Enforcement”. Once you are done selecting it, install the unsigned driver. Please note that this option is temporary and the driver signing will be activated again upon the next reboot.

Method 5: Windows XP Method

As mentioned earlier, if you are a Windows XP user, you would require following a different method instead of the ones mentioned above (1-4). The good thing is that doing this on XP is even easier.

1 Right click on My Computer

2 Choose Properties

3 Select Hardware tab under ‘System Properties’

4 Click on Driver Signing button.

5 Choose “Ignore – Install the software anyway and don’t ask for my approval”

6 Choose “Make this action the system default”.

7 Hit ‘OK’.

You are done with driver signing check process.
