Issue activating the trial licence of Indesign CC Server x64

I have downloaded and installed "Adobe InDesign CC Server | English | Windows 64-bit | 535.7 MB" from https://www.adobe.com/cfusion/tdrc/index.cfm?product=indesign_server.

I have also downloaded and installed APTEE to active the trial licence.

From an admin command prompt I've then run "adobe_prtk.exe --tool=StartTrial --leid="InDesignServer-10-Win-GM"", in the directory "C:\Program Files (x86)\Common Files\Adobe\OOBE\PDApp\Enterprise\utilities\APTEE\CS6\"

This returns the following:

I then try to launch Indesign server I get the following error.

If you can help I'd appreciate it.

Thanks,

Peter
