I know "Client for Microsoft Office" (Office Integration) is supported but I'm not sure that "Extension for MS Office" (Live Integration) is supported with Active Workspace? The "Integrations Matrix" isn't clear on that point so you may need to ask GTAC. AW4.0/Tc11.4 support the MSO online server (or local MSO 2016). Which version of MSO are you running?
Note: Word Live (previously part of Extensions) has been moved to "Client for MSO".
