Error exception when converting pdf to html file on window machine?

[junaidzubairshaikh]

I'm trying to convert pdf to html file on my window machine.
Following are the configuration lines.

    Config::set('pdftohtml.bin', 'D:\xampp\htdocs\poppler-0.51\bin\pdftohtml.exe');
    Config::set('pdfinfo.bin', 'D:\xampp\htdocs\poppler-0.51\bin\pdfinfo.exe');

I tried this with postman and attached image shows error. can you please help me to resolve this issue?
