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

Hi Prashant,

I just wanted to follow up on this thread. Did you find any PYTHON environment variables on your system ?

Our tools team suggest running these steps and let us know if it resolves the issue :

1. running the Windows Resource Checker as Adminstrator w/ following command:

sfc /scannow

2. Try simplifying the PATH to the minimal and execute.

Example: C:\Windows\System32>set Path=C:\Program Files\Python312\;C:\WINDOWS\system32;C:\WINDOWS;

C:\Windows\System32>c:\altera_pro\25.1_129\quartus\bin64\quartus_py

C:\Windows\System32>c:\altera_pro\25.1_129\quartus\bin64\quartus_py "print(\"hello\")"

hello

Regards,

Divya
