I study computer science in byu.edu, we choose the 3.4.3 vision. No matter which kind of computers or windows, I needed to download it from Microsoft store. Now I can download it directly from python.org

My environment: * Windows 10 * Microsoft Visual Studio 2019 * Qt Creator 10.0.1 (only as an IDE) * Python not installed This is what I did: 1. I downloaded https://www.python.org/ftp/python/3.11.4/Python-3.11.4.tgz 2. I extracted Python-3.11.4.tgz into C:\temp\Python-3.11.4 3.

So far, so good. Next, I tried to run embedded_python.exe. In order for the Python DLL to be available: 8a. I closed Qt Creator. 8b. In the Control Panel, "System", "Advanced system settings", tab "Advanced", "Environment Variables...", I added 'C:\temp\Python-3.11.4\PCbuild\amd64' to variable 'Path' under "User variables for dave". 8c. I restarted Qt Creator. 9. And now, when I ran embedded_python.exe: 20:14:06: Starting C:\temp\build-embedded_python-Desktop_Qt_6_1_3_MSVC2019_64bit-Debug\debug\embedded_python.exe...
