As mentioned in the chatterbox, you need to ensure that mysqladmin.exe exists on the machine in question, and that it's in your system PATH. Install via cpan:

c:\>cpan DBD::mysql
[download]

via PPM:

c:\>ppm install DBD::mysql
[download]

As always, you should read and understand the installation documentation. DBD::mysql, and README (which mentions an install.html file).
