General

The settings listed under General category allow users to access some of the key features of Userful™ such as Licensing, Failover Settings, Remote Control Settings etc.

Manage Licensing

With Userful™, Licensing is quickly and easily managed through the Control Center. The unlicensed version of Userful™ is fully functional, but will display a brief registration reminder on all attached displays every 20 minutes or so. To enable the full version, you need a valid license for each display.

Getting License Key Online
Manually Install License

To get your Userful host licensed online, Go to "Manage Licensing" link under Settings.

If you already have an activation code:

  1. Enter the Activation Code in the first box.
  2. Enter the maximum number of displays to be used in the second box.
  3. Press "Download and Install License" button to get the license key.

Note: The activation code is tied to a certain number of displays. The number of displays entered cannot exceed the number specified when activation code was created.

To get the "Activation Code", click "Get Activation Code" and submit the form.

You will need an active Internet connection to automatically install the license key or to submit the request for activation code.

Your web browser submits the basic system information to the license server as a part of the activation process. This information includes MAC address, Userful™ version and other hardware information.

The license key file(s) are installed automatically and take effect without rebooting the system.


Installing a License Key from a File
Install License Key

A Internet connection is required to use the activation code to install your license. If there is no Internet connection, email the MAC address or System ID of the Userful host you need to license along with your activation code to the Userful representative. They will generate a license key and send it to you as an attachment.

To install a license key from a file:

  1. Copy the file to the desktop of the system to be licensed or mount a USB flash drive containing the license key file.
  2. From the starting screen of the Licensing section, click on the button marked "Manually Install License File" under Settings > Manage Licensing > Replace License
  3. Click on the "Browse" button and navigate through the file system to the directory where the license key is saved. Select the license key file and choose "Open".
  4. Click on the "Upload License File" button. The license key file is installed automatically and takes effect after rebooting the system.


Increase Licensed Displays
Increase Number of Displays

If your contract allows, it is possible to increase the maximum number of displays connected to a given Userful host without replacing the license. To do this, click on the "Increase Displays" link under Settings > Manage Licensing

If desired, backup the existing license by clicking the "Backup your current license file” link in the dialogue that appears.

Enter the “Activation Code” and the new "Maximum Number of Displays". Click on the "Request Increase from License Server" button to complete the operation. Please Note: The new maximum number of displays entered must be greater than the current maximum.

The "License Details" will now reflect the increased Maximum Number of Displays.

Backing up a License File
  • To back up a license file, go to Settings > Manage Licensing and click the "Download/Backup current license".
    • This will open a dialogue box asking to confirm the file-saving operation. Click "Save" to save a copy of the license file with a ".bak" file extension in the /etc/userful/license/ directory.
Replacing an Existing License

Sometimes it may be necessary to replace a license on a working system; for example, to add more displays to the license. Contact your Userful representative if you have any questions about obtaining a replacement license.
To replace a license, go to Settings > Manage Licensing and click the "Replace License" button. Follow the instructions to either get a license through the Internet (if you have an activation code) or install a license file manually.
