Since Perl is open source software, it is part of the standard installation of almost any Unix / Linux system. ActiveState took this standard Perl installation as the basis and created its own configured and fully ready-to-use Perl distribution for Windows called ActivePerl. The package is easy to install in the system and still remains free software.
This wonderful distribution is perfect for everyone who is at least a little bit engaged in programming for the web, and, in particular, in the language of Perl. This package is useful for those who write and test various scripts. Both 32- and 64-bit versions of operating systems are supported. ActivePerl from ActiveState contains Perl translator for Win32 and Perl for ISAPI - plugin for IIS web server, PerlScript - ActiveX engine, and Perl Package Manager.
