unable to create executable using pyinstaller for kivy application containing pywinauto

[GoelPri]

Hi guys,
I was creating an executable for kivy application. And it uses a python script that requires pywinauto. After building the exe using pyinistaller on the spec file, I was unable to access the exe. It is throwing an error with thread issue concerning comtypes of pywinauto.

I built this on Ananconda.

I got the following error down below.

Has anyone encountered the same? Please help , need to resolve this soon

• Which hook/library isn't working?
  Pyinstaller is unable to create exe for python file with pywinauto reference.
• Does the error get raised while building or when running?
  Error when running the exe

This looks like a variant of pyinstaller/pyinstaller#6198, which is caused by win32com being imported before the other package that tries to set the thread mode (which in this case seems to be comtypes).

In PyInstaller-frozen application, win32com is automatically imported via the pkg_resources and win32com runtime hooks, so the work-around is to modify those runtime hooks to import the other package before they import pkg_resources and win32com, as per pyinstaller/pyinstaller#6198 (comment).
