[dispatch.cgi]
#!C:\Perl\bin\perl.exe
use Plack::Runner;
Plack::Runner->run('C:\Projects\Perl\Web\mywebapp/app.psgi');

The path separators should all go one way....

Looking at dispatch.fcgi ... it has the same "problem". So I imagine that is an assumption that "dancer" is making when creating the skeleton structure.
