    You need to remove the extra backslash

    This code:

    print "Content-type: text/html\\n\\n";

    Should be this:

    print "Content-type: text/html\n\n";

    EDIT

    Also, the first line in the script looks wrong.

    #!C:\xampp\apache\bin\httpd.exe

    This should be the path to Perl, not httpd.

    EDIT 2

    Finally, this all would have been easier for you to solve if you added these two lines after the first line in your script:

     use strict;
 use warnings;

    And run the script on the command line with the -c -w flags to compile-check and warnings-check your script, ie perl -cw yourscript.cgi. This will give you line numbers of errors and warnings in your script.

    Altogether, your script could look like this:

    #!C:\path\to\perl.exe

use strict;
use warnings;

my $command=$^V;
my $title = 'Perl Version';

print "Content-type: text/html\r\n\r\n";
print "
<html><head><title>$title</title></head><body>

<h1>$title</h1>

$command

</body></html>";
