Publishing Engine in Arbortext Editor

Hello All,

While Installation of editor, it ask for the Publishing Server - If I do not have Arbortext Publishing Engine - What should be the option ?

- Can I get the trail version for Publishing engine only - it comes with Windchill server only ?

  - Can I use the DITA OTK / Configure the OTK , if yes , how to setup /configure ? OR bydefault comes with the setup.

Thanks - MVK
