Hi Lin,
Actually I did indeed already test out Igor's suggestion, and we had already emailed each other outside this thread, but about the same problem. Unfortunately, also using a simple path name as PTETEST as I just re-tested once more (see screenshot), did not cure the filesize of 0 bytes.
In the mean time, I'm planning to use the .EXE resulting file, as there is no problem in maing .EXE files.
Thanks for your suggestions anyway !
