Does anyone know what that could be ??

Based on your description, it seems pretty obvious (and easy to confirm)
that Myprogram.exe needs to be run from its containing directory
("C:\myprogramfolder\run"). Try something like this...

import os
pwd = os.getcwd()
os.chdir('c:/myprogramfolder/run')
os.system("Myprogram.exe 1 1 acc 0")
os.chdir(pwd)

HTH,
