Appendix: Activating DeviceLock Licenses : Activating Client Licenses
  
Activating Client Licenses
To use DeviceLock, first activate the Core license. To use ContentLock, NetworkLock, and/or User Activity Monitor, activate the respective licenses in addition to the Core license.
The Core license is activated on computers running DeviceLock Management Console or DeviceLock Enterprise Server, that is, on computers used to manage DeviceLock Service on other computers, or to collect data from computers controlled by DeviceLock Service.
To activate the Core license, copy the file devicelock.lic to the DeviceLock installation folder, and then start DeviceLock Management Console to activate that file. By default, the DeviceLock installation folder is %ProgramFiles%\DeviceLock or %ProgramFiles(x86)%\DeviceLock on a 32-bit or 64-bit system, respectively.
The ContentLock, NetworkLock, and UAM licenses are activated on the same computers as the Core license. Copy the license files (such as dlcl.lic, dlnl.lic, and dluam.lic) to the DeviceLock installation folder, and then start DeviceLock Management Console to activate them.
When started, DeviceLock Management Console automatically recognizes the license files found in the DeviceLock installation folder, and activates the licenses accordingly. No additional actions are required.
 
Note:  
The name of DeviceLock license files originally has the .lic extension. When a client license is activated, the extension changes to .li_.
Multiple license files can be copied to the installation folder by assigning each of them a unique name. For example, devicelock.lic, devicelock1.lic, dlcl.lic, dlcl2.lic, etc.
Recommendations
After replacing an expired DeviceLock license file with a valid one, the About DeviceLock page in the management console may still display outdated license information. This problem is usually because the expired license file has been replaced by a valid one with the same name.
To resolve the issue, follow these steps:
1. Delete the license file from the DeviceLock installation folder. By default, the installation folder is %ProgramFiles%\DeviceLock or %ProgramFiles(x86)%\DeviceLock on a 32-bit or 64-bit system, respectively.
2. Start the registry editor (regedit.exe). In the case of a 32-bit system, delete the registry value HKLM\SOFTWARE\SmartLine Vision\LIC. In the case of a 64-bit system, delete the registry value HKLM\SOFTWARE\Wow6432Node\SmartLine Vision\LIC.
3. Copy the new license file to the DeviceLock installation folder, and then start the DeviceLock Management Console to activate that file.
