Hello Lester! Hello Tom!
I tried to use kpcli-2.7.exe under Win 8.1/64. It starts correctly, but after opening a file it fails with an error message, which indicates that libexpat-1_.dll is missing (the "_" is really there).
It seems, that there was a nearly equal problem some time before for strawberry perl:
(just to give a small hint). I just looked into the exe file via unzip -l and found, that the DLL isn't in there. I would try to add it by myself to check if this works, but I don't know your build env.
There appears to be some sort of packaging bug in XML::Parser::Expat that throws off PAR::Packer in assembling the list of DLLs to include. In my build script for Windows, I manually added libexpat-1_.dll as a library to include in the package and that seemed to resolve the problem.
