Solved
Dear Customer,
The URL should be: http://peservername:port/e3/servlet/e3 where peservername represents the appropriate Arbortext Publishing Engine server name at user site.
For more details about PE URL, please refer this article https://www.ptc.com/en/support/article/CS37985
However, you can uncheck this option (if you want) while installing Arbortext Editor and this URL can be provided later if you want to connect Arbortext Editor to Publishing Engine (refer the article shared above).
Please let me know if this helps. Thank you
Regards,
Manpreet Singh
