Well, i had much joy of my registered version! I needed to distribute a (tk/GUI-)perlscript that needed to run on several machines. And installing perl on all win32-machines isn't a good idea and a bit of an overkill.
Using perl2exe i could distribute the script as a single exe.
Personally, I feel this thread as a crack-thread because i think, if you really like perl2exe so much, register it. And you should respect this try-ware message.
If you don't like perl2exe, it's fee or it at all, ignore it, disadvice it, but don't crack it.
