The accepted answer doesn't really say what dlls they copied and in what places. I managed to fix it by copying the driver inside the sqldrivers directory relative to where the exe and qt dlls are (I'm using PySide but should work with PyQt4 as well). In setup.py:

setup(

    data_files = [('sqldrivers', ('C:\Python27\Lib\site-packages\PySide\plugins\sqldrivers\qsqlite4.dll',))],
    ...,

I had a really clever way to avoid making my users install vcredist--I copied the manifest and the DLLs into two places and all the errors about the MS DLLs went away. That's when I started trying to figure out this SQLite driver error.

I wasn't as smart as I thought. If I install vcredist all the "Driver Not Loaded" and "No SQL drivers found" errors go away. Arg.
