I used to use Perl2Exe here at "Big Pharma" for a few years just as a simple way to package a Perl application for distribution to user's desktops. Perl2Exe worked fine for what I needed, but cost more than I felt something like that should have given what it did at the enterprise level. PAR can do almost all of the same things and you can complain about the price. Granted Perl2Exe would encrypt your source code within the executable, but I didn't really care about that. About two years ago I started to make the switch over to PAR and haven't run into any problems other than the executables getting a few hundred K larger. Speed and stability both seem about the same.
