ProjectWise v8i (SS4) ... Windows 10 ... Microsoft Office 2013 integration module

With the following combination, we are encountering errors with the PW Microsoft Office Integration.

Example error: try to open Word file from PW Explorer results in "cannot login to data-source".

Windows 10

PW Explorer: 08.11.11590

PW MS Office 2013 and 365 integration: 08.11.11855

I guess that we need to change to the "Connect Edition" of Project Wise if we want to work on Windows 10 - correct?

Thx for reading.
