Hi all,
I wrote a gui library with ctypes and created a small program. Everything works fine. But after I created exe file with auto-py-to-exe, when I ran the exe file, it showed a message box. It says that No module named 'ctypes'

Oh I see. Okay. Anyhow, I found the problem.

sys.path.append(r"C:\Users\kcvin\OneDrive\Programming\Python\PyForms")

This is how I connect my gui library to my script.
I just commented it and copy pasted the script to "PyForms" directory. Then I compiled it an exe and it worked.
