Failed to launch NIOSV Command Shell. Getting (0xc0000142) application error.

We attempted to reproduce this issue on a Windows 10 machine but have not been successful so far.

The Tools team recommends trying standard Python 3.8.10, as it closely matches the Python 3.8.18 version used by quartus_py in Quartus 23.4.

Download Python 64bit 3.8.10 from:

https://www.python.org/ftp/python/3.8.10/python-3.8.10-amd64.exe

Run the Python installer after download completes. Select Custom Installation

uncheck Documentation

uncheck tcl/tk and IDLE

uncheck Python test suite

Click Next

Uncheck Associate files with Python (requires the py launcher)

Uncheck Create shortcuts for installed applications

Select Customized install location and use this path or any convenient short path.

c:\a\Python\Python38

Click install

Close

From command prompt:

cd <quartus installation>\niosv\bin\niosv-shell-files\

c:\a\Python\Python38\python main.py

As suggested above, set the PATH to minimal, we recommend installation to be at default c:\intelFPGA_pro\23.4 and run NIOS V shell.

    Hi BB and Divya,

    We have installed Python 3.8.10 as per your suggestion.

    Initially, everything was working well — the Nios V console functioned correctly even after multiple system restarts.

    However, today when I powered on my PC, I observed that the same error has reappeared.

    Best Regards,
