Sometimes these problems are simple typing mistakes. For instance, in your original post, you claim the error is "The program cannot start because Perl514.dll is missing", but in your link

pp --link=perl514.dll -o final.exe myScript.pl
[download]

you use lowercase perl514.dll.

Perl514 !~ perl514 .Possibly you have a spelling typo, or maybe you need to specify the path to dll with more accuracy? Like ./perl514.dll or maybe it's full path. There are alot of possible causes of this glitch, see perl514.dll issue with pp. You might need to set the -L for the library directory path in addtion to the dll file.

Good luck hacking out these possibilites.
