Hi,
I noticed you want to install the latest version of this software, however Windows 10 Enterprise 2015 LTSB is intend for those computers who will not have frequent update or changes. I have downloaded the latest Displaylink USB graphics software released version note and found it support system version Windows 10 version 1607 and upper. But Windows 10 Enterprise 2015 LTSB have same system build with Windows 10 version 1507 which is previous than that software requirement.
So try to contact with DisplayLink support to check if any previous version of this software will support Windows 10 Enterprise 2015. Or we could upgrade Windows 10 Enterprise 2015 to Windows 10 version 1607 LTSB.
Bests,
