Hi Roderich, Thanks for your great help and I was able to install PAR::Packer which generate a standalone binary on Windows. Since the binary is generated on Windows, it can only run on Windows where no Perl was installed. Although it says "Cross platform", it doesn't mean the binary generated on Windows can be run on Linux/Unix. Is it correct?
