In this article, you learn what to do if an USB-eLicenser is not recognized/displayed by the system or the eLicenser Control Center or if a license seem to be missing on the USB-eLicenser.

Updating the eLicenser Control Center

Most USB-eLicenser issues can be solved by installing the latest eLicenser Control Center, which also contains a USB-eLicenser driver update. The latest version for your operating system is available here.

After the installation has been completed, open the eLicenser Control Center and apply the 'Maintenance & Online Synchronization' by clicking on "Perform Maintenance Tasks" (or click on the 'Maintenance' button if not shown).

Reinstalling the eLicenser Control Center

If the USB-eLicenser still is not recognized or in case the installation fails, please reinstall the eLicenser Control Center thoroughly, following these steps:

• Unplug the USB-eLicenser.
• Restart your computer.
• Uninstall the eLicenser Control Center.
  ▸ Windows: Control Panel > Programs and Features/Apps and Features
  ▸ Mac: The eLicenser Control Center installer contains an uninstaller, too.
• Restart your computer.
• Install the latest eLicenser Control Center.
• Only after the installation of the eLicenser Control Center has been completed, re-connect the USB-eLicenser.
• Windows: Wait for the driver to be installed.
• Start the eLicenser Control Center (Applications/Programs).
• Apply the 'Maintenance & Online Synchronization' by clicking on 'Perform Maintenance Tasks' (or click on the 'Maintenance' button if not shown).

Further troubleshooting steps

In case the thorough reinstallation didn't solve the problem, please follow these instructions:

• Connect the USB-eLicenser to a different USB port. Try all ports on your machine. Ports on the rear often work more reliably.
  Windows: If it is the first time, a USB-eLicenser is connected to that port, the Windows Hardware Detection Wizard should come up. Do not cancel it. Instead, guide the Wizard to install the USB-eLicenser driver automatically.
• Normally, it is best to connect a USB-eLicenser directly with the computer. However, certain difficulties can be solved by using a USB hub. Self-powered USB hubs (those with an own power supply) are usually the best choice. USB ports on keyboards tend to be less reliable, not least because they often do not provide sufficient power.
• Disconnect USB devices you don't need and/or uninstall drivers of unneeded devices.
• On some computers, USB 2.0 ports work more reliable than USB 3.0 ports.
  Windows: Try if disabling USB 3.0 support (BIOS or UEFI settings) helps.
• Verify if the USB-eLicenser is working on a different computer. Running a function test is easy: Simply install the eLicenser Control Center on a second machine and connect the USB-eLicenser. If the USB-eLicenser is being recognized on the alternative computer, it is a system-specific issue and not a USB-eLicenser failure.
• On rare occasions, a manual uninstallation of eLicenser Control Centers might be necessary. A detailed explanation on how to remove eLicenser Control Center related files from your system can be found here.
• Mainly Windows: Virus scanners, internet security programs and tweaking tools can interfere with the installation of the eLicenser software and drivers by blocking system folders and files. Please disable these applications during the installation.
• Windows: Verify if a chipset driver update is available from the manufacturer of your motherboard/computer to make sure the USB controller works optimally with your operating system. If you are not sure where to find chipset driver updates for your computer, contact your dealer or the manufacturer of your computer, or have a look at the manual of the motherboard.
• Windows: Running the eLicenser Control Center and/or a Steinberg application in Compatibiliy Mode can cause license issues. To check whether Compatibility Mode is enabled or not, right-click on the corresponding shortcut on the Desktop, select 'Properties' from the contextual menu and switch to the 'Compatibility' tab. Alternatively, you can also right-click on the application's *.exe file.
  These are the paths for the eLicenser Control Center:
  Windows 32-Bit: C:\Program Files\eLicenser\eLCC\eLCC.exe
  Windows 64-Bit: C:\Program Files (x86)\eLicenser\eLCC\eLCC.exe   
• Windows: A note for users with nVidia nForce3 chipsets: Some old Steinberg Keys (key numbers are xxx 523 326 or lower) do not work with this specific chipset family and need to be replaced with a new eLicenser. USB-eLicensers are available from any Steinberg dealer and, of course, in our online shop. Alternatively, connect the USB-eLicenser to a USB hub. This will separate the problematic chipset from the USB-eLicenser.
