Error when running pyinstaller (1920, 'LoadLibraryEx', 'System cannot access the file')

Question

Im trying to compile my python script to an exe so that i can send it to friends that can use with without having to install python, but im running into an issue and cant find a solution.

i found a similar issue at Pyinstaller win32ctypes.pywin32.pywintypes.error: (1920, 'LoadLibraryExW', 'System cannot access the file')

but cant post there except as a answer, i tried to add permissions and unhide the 'WindowsApps' folder but nothing seems to work.

Here is what cmd is giving me when running pyinstaller

and 'Systemet kan inte komma åt filen' is swedish for 'System cannot access the file'

After extensive trial and error i just gave up for now and had my friends install python and the modules required (i whipped up a quick batchfile) — Kingwood, Nov 14 '19 at 08:29

We don't support the Windows store version of python due to the fact that PyInstaller can't access the DLLs required to build you application. Please use a virtual environment of some kind or install python from https://python.org

I had the same issue with this, apparently it's something to do with shared file systems.

The solution in the post you provided helped me sort the problem, follow this link to guide you to create a virtual environment:

https://www.google.com/amp/s/www.geeksforgeeks.org/python-virtual-environment/amp/

If you have any issues with pyinstaller not being 'recognised as an internal or external command' dont forget to add the virtual environment pyinstaller module to your environmental variables.

I had exactly the same '(1920, 'LoadLibraryEx', 'System cannot access the file')' problem with Pyinstaller and after much thrashing on the problem decided to clean up my Python environment. So I uninstalled Python 3.6 and 3.7 then uninstalled PyCharm and Anaconda.

Then installed Python 3.8 and Pip 3.8 and then Pyinstaller and IT WORKED!!! My hunch is the problem was a conflict between 3.6 and 3.7 but that is just a hunch. I do think PyCharm and Anaconda are great products - - I'm just going to be WAY more careful about my Python environment from here on out.

[BTW Pyinstaller worked flawlessly first time on my Linux development box.]
