Hi Rene,
Thank you for message, indeed the problem was in PATH variable:
spawnvp() function failed to start process if it has to find the executable using environment PATH variable, but meets the path to the CD drive with no cd inserted during PATH veriable parse.
However, the problem was not connected with PATH variable length.
Thank you,
