Is there a specific dependency on SQL client install etc for this version?

Product: ProGet
Version: 3.6.1

This error means that the connection string in the installed product doesn't work for the user installing the software. Most likely, you don't have access to the database or server.

I think the discussion here http://inedo.com/support/questions/3126 may be related as well.
