Why an 'exe'? Why not pare perl down to the bare needed libs
plus LWP::Simple and give him a batch file to run it all,
w/ everything unpacked in one dir or something. He must
have pkunzip/netzip/winzip somewhere or make one of those
self extractors out of it. Best part is, as you fix up
your code, you can then just send him the updates ... or
teach him perl. The best/easiest: the activestate install,
for example, is pretty swift and clean. Run that, add your
script to the desktop ...
