Python2/3 difference at DLL load

[deusyss]

Hi,

I've different comportement of comtypes on several computers. Same windows, same pycharm.

At the beginning, i was thinking about an environment problem, but in all cases, it works with Py2 and not for Py3. So there is a difference. Py2 and Py3 use the same comtypes version. The "gen" package generate files but not the sames.

1st PC: win7 pro SP1, last pycharm, winpython 3.6.1.0QT5 => KO 1st PC: win7 pro SP1, last pycharm, winpython 2.7.10.3 => OK 2nd PC: win 7 pro SP1, last pycharm, winpython 3.6.1.0QT5 => sometimes work 2nd PC: win 7 pro SP1, last pycharm, winpython 2.7.10.3 => OK

Perhaps someone has an idea?
