Page Contents



Online Licensing System is a secure way to license products online as a highly-encrypted centralized online system that manages licenses for all your systems. Additionally, the Online License System also provides for users to "borrow" licenses from their online accounts and work offline without having a hardware dongle, for up to 14 days at a time.


Installation Process

On the Linux OS, please use your local user with the sudo command instead of the root user to run the installer.


1) Run the License Server installer that is included with the Chaos Group product installation package or download the License Server installer separately from the Downloads section of the Chaos Group website (you'll need to be logged in to access it).


2) Please read over the license agreement. To continue with the installation process, click the I Agree button.

3) You can choose to accept the default installation parameters, or use the Customize button to change these parameters.


If you are installing for the first time then Activate during installation will be checked. If you have a previous version of the Online License Server installed this will be unchecked.

Windows Default Install path - C:\Program Files\Chaos Group\VRLService\OLS


Linux Default Install path - /usr/ChaosGroup/VRLService/OLS


OSX Default Install path - /Applications/ChaosGroup/VRLService/OLS
