Hello Manoj,
The thing is that you are using an old version of Adaxes while the instructions you are referencing are only for the latest version. To activate your license key:
- Unzip the license.zip archive.
- Navigate to the folder where Adaxes Service is installed, which is C:\Program Files\Softerra\Adaxes 3\Service by default.
- Open the License folder.
- Copy your license key file (license.admlic) to the folder.
- Restart Adaxes service.
If you have multiple instances of Adaxes service sharing common configuration, activate your license key for each instance.
