I've installed Office 2013, previously I had connect my postgreSQL DB via ODBC, but I read that I can connect it with Power Query which seems better.
However the installation of npgsql is daunting, so I installed npgsql using the nuget command line.
However I'm ecountering the same error...
What can I do?

The screenshot is in italian, however it is saying npgsql is missing
