Perl distribution is available for a wide variety of platforms. You need to download only the binary code applicable for your platform and install Perl.
If the binary code for your platform is not available, you need a C compiler to compile the source code manually. Compiling the source code offers more flexibility in terms of the choice of features that you require in your installation.
Here are the steps to install Perl on the Windows machine.
Follow the link for the Strawberry Perl installation on Windows http://strawberryperl.com.
Download either 32bit or 64bit version of the installation.
Run the downloaded file by double-clicking it in Windows Explorer. This brings up the Perl install wizard, which is really easy to use. Just accept the default settings, wait until the installation is finished, and you're ready to roll!
