The software doesn't appear to be available for downloading. As a result of my search queries, I have found only an updater that brings the software's version to 1.2. There is nothing else about this software related to documents, troubleshooting data, user guides, manuals, etc.
If you have the software installed on your PC, then go to Help > Contents and switch to Search. Type paths and you should see all the available topics.
Secondly, go to File > Save as and note the location. The next time you're working with the software, the content will be in the previous saved location.
