    Welcome, and thanks for taking the time to format your post correctly. Could you please post the contents of hello.pl?

    What does this emit? 
    perl> perl -v

    And, raising another possibility, M$' "Access Control" may be getting in your way... as it does not always behave as you might expect, despite your "Admin" status.

    But from your description, you did put \Perl\bin in your path. That's good.

    However, your "hello.pl" file does NOT belong in "C:\Perl\bin" or "C:\Program Files\Perl\bin" because that's for Perl itself.

    Instead, create another directory, outside the AC restricted zone... perhaps, "C:\Libraries\scripts" or, better yet, "D:\scripts" and try running "hello.pl" from there.

      Hi thanks for response..

      #!/usr/bin/perl -w

print "Hello, World!\n";

      is my script..

       perl> perl -v

      just goes back to the command prompt.. I have right clicked on the cmd icon in the start menu, copied to desktop and set properties so am running the command as administrator. I have reinstalled the application 3 times.

      I tried moving the file to an external drive..

        If running "perl -v" "just goes back to the command prompt (without any error message from 'doze?) you have a problem that I can't grok at the moment.

        If cmd.exe didn't find perl it would be expected to spit out a complaint on the order of "perl is not recognized as an internal or external command, operable program or batch file."

        But, OTOH, if cmd found perl and perl didn't respond to your request for version information, that would say Perl itself is broken. Yet that seems to be at odds with the "Access denied" message you reported earlier.

        So, without a clue, perhaps you'll answer the question above... and report what Win7 tells you when you enter "path" at the command prompt, and what distribution of Perl you've installed repeatedly (and whether you were careful about removing all traces of the previous version on each re-install).

        HTH ...but I'm not wildly optomistic :(

        Perhaps I misinterpreted what your command prompt looks like. If you're doing something like: 
        C:\ perl> perl -v

        [download]

        ... then that's not even close to what I meant, and I'm quite sure I don't want to try it to see what happens.

        Here's what I meant for you to try, for whatever your command prompt is:

        perl -v

         E:\>perl>hello2.pl

        You're overwriting hello2.pl

        You're supposed to type     perl hello2.pl

        perl as in perl.exe or C:\perl\bin\perl.exe or c:\strawberry\perl\bin\perl.exe ...
