Terminal Emulator option not shown in UFT 12.5.

Installed UFT trial version 12.5 Build 3785 along with Terminal Emulator add-in. While launching the UFT, getting the message as "UFT Terminal Emualtor support is not configured correctly. Either the terminal emulator is not installed on your computer, or the HLLAPI DLL was not found".

Please help to resolve this issue as i need to start a sample test scripting in AS400.
