When you launch Perl via the .pl association, @INC contains only ".". When you launch Perl via the PATH, it contains the three items it should. You appear to have two Perls installed.

What do you get from 

>assoc .pl
.pl=Perl

>ftype Perl
Perl="C:\Perl64\bin\perl.exe" "%1" %*

[download]

(Replace "Perl" in the second command with what's right of the "=" in the output of the first.)

If you don't get the same output, you can fix it using 

ftype Perl="C:\Perl64\bin\perl.exe" "%1" %*

[download]

(Again, replace "Perl" with the appropriate value.)

Update: Cleanup. Added fix.
