Specification

• pywebview version: 3.3.3
• platform / version: Windows 10.0.19041.488 (WinBuild.160101.0800)
• pyinstaller version: 4.0

Description

I create a workflow to freeze the hello world pywebview aplication using pyinstaller at github actions. The executable don't work at my machine. I try the same executable at five machines (include my own) and the app run only at two. Also, the app runs at my machine if I freeze it at my own machine.

main.py

import webview 
webview.create_window('Hello world', 'https://pywebview.flowrl.com/')
webview.start()

python-app.yml

Judging by the error report, it cannot find Python.Runtime.dll (as required by pythonnet). Try copying this file to your frozen folder and see if it makes a difference. The dll is located in the package directory. Normally the pythonnet hook should take care of this, but it may be that Pyinstaller 4.0 broke something.

[igormaraujo]

There is the Python.Runtime.dll at my frozen folder. If I use the the Python.Runtime.dll from The GitHub Action workflow hosted visual environment, it don't work. However, if I use the dll in the package directory from my own machine, it is work. I am think that there is some compatibility problem with the dll compiled at GitHub Actions.

The error message says

Have you tried to enable the loadFromRemoteSources switch?
