That’s an odd issue. Give this a try:
-Restart Windows.
-unplug your eLicenser.
-Close everything.
-Uninstall the eLicenser Control Center.
-Restart Windows again to make sure that NOTHING is using any eLicenser-related files.
-After starting Windows, plug your eLicenser into an USB port (Preferably USB 2 if possible. USB 3 ports are usually blue).
-Temporarily disable any Antivirus software, such as Windows Defender/Microsoft Security Essentials.
-Run elc-installation-helper.exe again.
This will hopefully make it work this time.
