Was beta4 installed by the MSI installer? It's really supposed to take
care of that. libpq.dll should be in SYSTEM32, and shouldn't be removed
until *all* instances are uninstalled. I have tested this several times,
and it has always worked in my tests.

Do you ahve any other software installed that may have provided a
libpq.dll`?
