It looks like on PCs other than the 2 I tried Python doesn'like these
lines of code:

    def CheckForDatabase(self):
        """ Checks if a database exists. If it doesn't, creates one anew. """

        # We build the database inside the user config folder, where we
        # also create a sub-directory called /.GUI2Exe
        standardPath = wx.StandardPaths.Get()
        configDir = opj(standardPath.GetUserConfigDir() + "/.GUI2Exe")
        configDb = opj(configDir + "/GUI2Exe_Database.db")

        if not os.path.isfile(configDb):
            # No database
            if not os.path.isdir(configDir):
                # And no directory. Create a new one.
                os.mkdir(configDir)

        return configDb

So, it doesn't create the directory and bsddb is right in
complaining... I don't really know why, I was just trying to create a
directory called  /.GUI2Exe under the user configuration directory
which for me is:

C:\Documents and Settings\Andrea\Dati applicazioni

Curiously enough, it works well here :-( :-(

BTW, I noticed I forgot to include the manifest file for Windows
(!!!!!), so the executable didn't look that much XP-style :-( . I
re-uploaded another version right now. However, I still don't know the
reason why the program can't create that particular directory. Maybe
someone more knowledgeable than me can explain it.

I tried to install il to see if could be acutally __import__ed,
because, for example, on Windows cx_freeze and PyInstaller can not be
imported, do not live under site-packages and so on... cx_Freeze is an
executable on Windows!!!

I have no idea about that... surely Robin knows the answer, he has
developed bsddb for quite long time... but maybe is just my fault, I
never worked with bsddb before :-D
