New install will not connect to Farm

I'm attempting to use Metalogix Expert for the first time.  I can not get it to connect to my farm.  I can get it to scan a single site but it absolutely will not connect to the farm.

Is this supposed to work?  Do I need to install this software on the Farm itself?  Instructions say I don't.

Please let me know as this is stage one of evaluating Quests SharePoint software and I'd hate to leave disappointed.
