Updating to ActivePerl 5.16.3.

   I’ve read this and found the new 5.14.4 and 5.16.3 versions include these fixes. So I update to 5.16.3.

1. Download ActivePerl-5.16.3.1603-MSWin32-x86-296746.msi.
2. Uninstall the previous version.
3. Install ActivePerl-5.16.3.1603-MSWin32-x86-296746.msi by default.
4. Run cmd.exe
   perl -v[enter]
   You have “This is perl 5, version 16, subversion 3 (v5.16.3) blah-blah-blah”.

   Rewrite the first line of printenv.pl.
         #!D:/programs/perl/bin/perl.exe　　—>>　　#!C:/perl/bin/perl.exe
   Copy printenv.pl to your cgi-bin directory and check http://YourDomain.com/cgi-bin/printenv.pl.
   If you have the ENV list, your installation is complete.
   Delete printenv.pl.

   That’s it.
