If you need to transfer the license key to a new or different computer, you need to first deactivate the license key in the computer where it has been activated. Alternatively you can manage your license keys and activations from the Customer Portal.

Open the application GUI, then click on the top menu Help -> License Status. It will open the Activator window, click the button "Deactivate" to deactivate the serial key. Once the key has been deactivated, you can use the key in a new or different computer. Alternatively you can manage your license keys and activations from the Customer Portal.

The license works for all users of the computer.

You should allow/exclude all .exe and .dll files located in the following folders:

C:\Program Files (x86)\NoVirusThanks\NVT License Manager\
C:\Program Files\NoVirusThanks\SysHardener\

Then restart the PC. If problem persists, uninstall and re-install SysHardener.

It is possible your security software is blocking following processes:

C:\Program Files\NoVirusThanks\SysHardener\SysHardener.exe
C:\Program Files (x86)\NoVirusThanks\NVT License Manager\NVTLicenseManager.exe
C:\Program Files (x86)\NoVirusThanks\NVT License Manager\NVTActivator.exe

Make sure they are allowed/excluded in your other security software. Then try to restart the PC and if problem persists, uninstall and re-install SysHardener.

When you get the activation window, try to click the "Deactivate" button (with an Internet connection active), and then activate again the same license key. This way the license is deactivated, and then re-activated, this should resolve this specific issue.

If the above doesn't work, try to delete this registry value with regedit (Registry Editor):
HKEY_LOCAL_MACHINE\SOFTWARE\NoVirusThanks\SysHardener\ActivationIssues
Then try to open again the program.

You need to allow outbound connections to following processes:

C:\Program Files (x86)\NoVirusThanks\NVT License Manager\NVTActivator.exe
C:\Program Files (x86)\NoVirusThanks\NVT License Manager\NVTLicenseManager.exe
C:\Program Files\NoVirusThanks\SysHardener\SysHardener.exe

All the above executables are digitally signed.

Run the setup.exe file with following parameters:

setup.exe /LICENSEKEY=XXXXXX-XXXXXX-XXXXX-XXXXX /VERYSILENT /NORESTART

Overwrite XXXXXX-XXXXXX-XXXXX-XXXXX with your license key and make sure all the computers have an active Internet connection (very important). The program will be installed in the system and automatically activated.

Run the setup.exe file with following parameters:

setup.exe /APPLYSELECTED="C:\Path\To\Tweaks.ini" /VERYSILENT /NORESTART

The above commands will install the program in the system and then, once done, the program will automatically apply the specified tweaks from the INI file.

The product will stop working and it will show the Activator GUI saying the license is expired. You need a valid (unexpired) license key to keep using the product.
