Thank you so much for the reply. I have looked things over and modified the code to run with the use if pragma:

#BEGIN {
#    my $LoadModule = ($^O ne 'MSWin32') ? 'UnixSecurity' . '..pm' : '
+Win32Security' . '..pm';
#    eval "require $LoadModule; 1;" or die $@ if $LoadModule;
#    $LoadModule->import();
#
#}

use if ($^O eq 'MSWin32'), 'Win32Security';
use if ($^O ne 'MSWin32'), 'UnixSecurity';

I am still getting the error and I am not sure why?

C:\Perl>TestLoad.pl Can't locate Win32Security.pm in @INC (you may need to install the Win32Security module) (@INC contains: C:/Perl C:/strawberry/perl/site/lib C:/strawberry/perl/ vendor/lib C:/strawberry/perl/lib .) at C:/strawberry/perl/lib/if.pm line 13. BEGIN failed--compilation aborted at C:/Perl/SecurityV1.pm line 40. Compilation failed in require at C:\Perl\TestLoad.pl line 5. BEGIN failed--compilation aborted at C:\Perl\TestLoad.pl line 5.

Based on my current understanding, I believe the revised code should work.
