Got this error on my pyzbar program after I converted to exe with pyinstaller

Question

The error message is:

PyInstallerImportError: Failed to load dynlib/dll 'C:\\Users\\PETERM~1\\AppData\\Local\\Temp\\_MEI143202\\pyzbar\\libico
nv-2.dll'. Most probably this dynlib/dll was not found when the application was frozen.

Seems like it was answered by r92546024 on GitHub: link

Excerpt:

1. if you have MSVCR120.dll missing when execute the exe, you need to install C++ package

2. You can put the libiconv.dll & libzbar-64.dll in the exe work folder.
   The exe file will use the dll in the same folder by first
   Note:
   You can get the two dll from C:\Python35\Lib\site-packages\pyzbar and then copy to the exe folder

Answer 2

You can try to add the dll directly to the executable file's directory and also use the --add binary when using pyinstaller to build the executable. You can find the 2 dll from C:\Users\user\PycharmProjects\pythonProject\venv\Lib\site-packages\pyzbar if you are using pycharm
