Well, there are several problems that cause the behaviour that you 
describe above.

First, I added the hook_PySide() method in hooks.py because I noticed
that pyside programs only work with bundle_files == 3.  This function
can probably be removed.

Second, please replace line 87 in Lib/site-packages/zipextimporter.py
(which is part of py2exe): "        except Exception:" by this code:
"        except ImportError:".  This code did hide the real problem
with PySide.

When you now build an exe from a simple pyside script (with bundle_files 
set t0 0, 1, or 2), you get this when you start the exe:

Traceback (most recent call last):

FileNotFoundError: [WinError 3] Das System kann den angegebenen Pfad

So, the exe still does not work but we see the problem:
the call to _utils.get_pyside_dir() in PySide\__init__.py fails.
The reason is that in PySide tries to determine the real filename
of the QtCore.pyd file; but this fails.

So, the problem seems to be in the PySide code; it does not work when
PySide is loaded from a zipfile.  I wonder if the code in
PySide/__init__.py: _setupQtDirectories() is really needed; for my tests
the simple exe works ok when I comment out this function.  Maybe you can
check with the PySide developers?
