perl 使用pp生成exe时出现错误，请指教

我用perl5.10.1版本，安装步骤如下：
在ppm中，先安装Parse-Binary, Win32-Exe, Module-ScanDeps, PAR-Dist,Getopt/ArgvFile，都成功
然后，
用迅雷在网站http://www.perl.com/CPAN/authors/id/S/SM/SMUELLER/，
把PAR-Packer-0.982-MSWin32-x86-multi-thread-5.10.0.par.bin 文件下下来，并用如下命令安装：

C:\Perl>perl -MPAR:ist -e "install_par('PAR-Packer-0.982-MSWin32-x86-multi-thread-5.10.0.par.bin')"
安装成功了，提示：

此时执行

提示如下错误信息：

请问是怎么回事啊？我还装了一个perl.5.8.9，用的PAR-Packer-0.980-MSWin32-x86-multi-thread-5.8.8.zip，提示错误信息一样，看来不是版本的问题，不知谁能帮助指教啊。

自己顶一下
