Just clicking on it will do

Have you tried it?

Because if it isn't set up correctly, or not the way you want it, you could do the following:

• Make sure the script has the extension you want to have connected with Perl. I see .pl a lot, but I prefer .perl
• Right click that file and follow the instructions to connect the extension with the Perl executable perl.exe.

Voilą!
