Hi and welcome to devnet,

One thing you can do is use Dependency Walker to check whether all dependencies are met for the PostgreSQL plugin.

What Qt package did you install ?

QT 5.6 community for windows 64

Which one ? There's at least three different packages for the various compilers available on Windows.

msvc2015-64

Did you check that the PostgreSQL you installed is also built with that version of Visual Studio and in 64 bit ?
