Remote Access Clients E75.30 does not have a planned release for Win8.1 and you need to move over to E80.
The E80-train used to require its own management server and its own licenses in order to be administrated.
E75.30 moves to E80.42 which supports Windows 8.1.
E80.50 > Managed using SmartEndpoint on R77 SM.
