Error. You have specified 'C' as an Inline programming language.

I currently only know about the following languages:
    Foo, foo

If you have installed a support module for this language, try deleting the
config-MSWin32-x64-multi-thread-5.020000 file from the following Inline DIRECTOR
Y, and run again:

    C:\Perl\cpan\build\AI-NNEasy-0.06-CmMDft\_Inline

(And if that works, please file a bug report.)
