Hello,I'm having trouble with the Nios V Command Shell; specifically, I cannot start the shell (niosv-shell.exe) or the RiscFree IDE. Sometimes the program starts, and sometimes it does not.Operating system: Windows 10 19045.5737 version 22H2.Tool: Quartus Prime Pro 23.4I'm getting an application error 0xc0000142: I've already reinstalled the Quartus tool a few times.Also followed the steps from the link below.https://thegeekpage.com/how-to-solve-application-error-0xc0000142-in-windows-10/still getting the same issue.

Hi Prashant, It appears you’ve already reinstalled the tools, yet the issue still persists.Are there any other files remaining in the Quartus installation directory? Could you perform a completely clean install to ensure no outdated files are left behind?Let me know if that works.Regards,Divya

Hi Divya,Thank you for the reply,Yes, I have make sure that there is no outdated files in installation directory.Best Regards,Prashant Gohel

Hi divya,Also the similar issue faced in some of my colleague system, in which we have intall Quartus 24.3 prime pro first time.Best Regards, Prashant Gohel

Hi Prashant, We are not aware of any known issue and I cannot reproduce this at my end. It's interesting to see that two versions (23.4 and 24.3) far apart from each other show the exact same behavior. Do you only see this problem on a Windows machine ?Can you share a screenshot of how the environment variables are setup. Regards,Divya

Hi Divya, We haven't tried on Linux system. As we only use windows system for Quartus tool.Best Regards,Prashant Gohel

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

Hi Divya and BB,

Thank you for sharing the information, as it required Administrator access, I will share this step with admin team and check. It required few days. Will share the result with you.

Did you find any PYTHON environment variables on your system ?

I didn't get any path with PYTHON in environment variables.

Hi Divya,

We have executed the suggested steps in administrator mode. But while running the qurtus_py we are getting the same application error message.

  Sorry to hear that didn't help.
  Could you please try running 'quartus_sh -s' to see if Quartus starts successfully?

Hi Prashant,
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 be the minimal and run quartus_py
Please let us know if this makes any difference.
Regards,
Divya

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,
