I've just got a VM going to test TRIM v7.1 and Office 2010 integration.
Windows 7 x64, TRIM 7.10.1132.
In TRIM, I configured the integration as per the screenshots I've attached. (NOTE: I know the Word button is unchecked, but I did check it... more to follow)
However, integration is not working. In Word, if you manage the COM Add-ins via the Add-Ins option, you get an error about the HP TRIM Add-in for Microsoft Office, that says:
Load Behavior: Not loaded. A runtime error occurred during the loading of the COM Add-in.
