Crash log parser

I am having trouble using the crash log parser on a Windows machine using mbed Studio. The parser with txt, elf, and map files all reside in the same directory:

C:\Users\wjgdm\Mbed Programs\TaleGator_Project\BUILD\LPC1768\ARMC6

When I run the command script:
python crash_log.txt TaleGator_Project.elf

I receive the error message below:

Traceback (most recent call last):
File “”, line 199, in
elfhelper = ElfHelper(args.elffile, args.mapfile)
File “”, line 36, in init
op = check_output([_NM_EXEC, _OPT,]).decode(‘utf-8’)
File “c:\ProgramData\Mbed Studio\mbed-studio-tools\python\lib\”, line 411, in check_output
File “c:\ProgramData\Mbed Studio\mbed-studio-tools\python\lib\”, line 488, in run
with Popen(*popenargs, **kwargs) as process:

restore_signals, start_new_session)
File “c:\ProgramData\Mbed Studio\mbed-studio-tools\python\lib\”, line 1207, in _execute_child
FileNotFoundError: [WinError 2] The system cannot find the file specified

I would appreciate any help here. I have returned to mbed after a 5-year absence. My program was written under OS2 for LPC1768 and I have been working to adapt it to the latest OS6. I am stumbling through this process and encountering a fault.
