No solution worked. I can not write/copy in the Programs folder. I packed the script in an exe in order to run it as Administrator (do not know how to run a script as Administrator), but nothing is written in the Programs folder.

However, there are some programs installed in the same folder doing automatic updates, which I guess means automatic replace some files in the installation folder. I am a bit scared of looking into the "writing rights" matter. Just seems to complicated for me.
