this is actually a bug in the eLicenser Control Center (eLCC) software.
As far as I known, this issue occurs only on Windows systems that are set either to Turkish or Azeri language; to work around this issue, you need to (temporarily) change your system’s language settings, e.g. to English.
On your Windows-8.1 system, this needs to be done using the “Format” setting (see attached screenshot):
Open the “Clock, Language, and Region” Control Panel, then click “Change date, time, or number formats”.
In the “Formats” tab, choose a compatible format (e.g. “English (United Kingdom)”).
Now, when launching eLCC, its interface should be localized in English.
Hope this helps!
