After the initial failed installation, I also excuted the step "Serialize using APTEE (Online)" of InDesign Help | InDesign CC Server 2014 Release Notes with Adobe Provisioning Toolkit Enterprise Edition for CS6 (Mac). The return code was 0!
It sounds like you're installing CC, but you linked to CC 2014 release notes. Make sure you are using the version 9 (CC) command instead of the version 10 (CC 2014) command.
True, I mixed the commands as I wasn't aware that a version 10 of Indesign CC Server exists. I used the latest of AEDP.
OK, I also executed the version 9 (CC) commands and tried to install the Indesign CC Server. The installation failed with the same error!
Maybe I have for access to the latest of Indesign Server (version 10 / CC 2014)?
PS: Installation of Indesign Server (CC / version 9) with commands of version 10 (CC 2014) worked without problems.
