How can I add nomenclature in latex document by solving mentioned error?

Process started: makeindex "Thesis".nlo -s nomencl.ist -o "Thesis".nls
Index style file nomencl.ist not found. Usage: makeindex [-ilqrcgLT] [-s sty] [-o ind] [-t log] [-p num] [idx0 idx1 …]
Process exited with error(s)

Nomenclature was working fine earlier but now its not working.
My preamble looks like this:

usepackage[utf8]{inputenc}
%usepackage[hidelinks]{hyperref}
usepackage[english]{babel}%allow to write and suggest hyphnation and all
usepackage{microtype}%improve justification in whole document
usepackage{enumitem}%list items better
usepackage{index}
usepackage{lmodern,amsmath}
usepackage{amsthm}
usepackage{amsfonts}
usepackage{amssymb}
usepackage{multirow}
usepackage{calc}
usepackage{siunitx}
usepackage{graphicx}
usepackage{gensymb} % to enable degree command
usepackage{textcmds}

% to show symbols in PDF bookmark link
usepackage{textgreek} 
usepackage[
hidelinks,
pdfencoding=auto, % or unicode
psdextra,
]{hyperref}[2012/08/13]
%hypersetup{pdftex,unicode,colorlinks=true,allcolors=black}
usepackage{hypcap}
usepackage{bookmark}
usepackage{cleveref}

usepackage[pdf]{pstricks}
usepackage[labelfont=bf]{caption}% this will make figure x.x bold
usepackage{fancyhdr}% good image and header footer
usepackage{float}
%usepackage{floatrow}    
usepackage{subfig}
usepackage{caption}
%usepackage{subcaption}
usepackage[toc,page]{appendix}
usepackage[verbose]{wrapfig}
%renewcommand{baselinestretch}{1.5} 
graphicspath{Images/}

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% At this stage I am adding nomencl package.
usepackage[intoc]{nomencl}
makenomenclature
renewcommand{nomname}{Nomenclature}
usepackage[nottoc]{tocbibind}
.........................................

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

My tex file look like this:

%[1] Begining Thesis as a report
documentclass[a4paper,12pt,twoside]{book} % For print add ",twoside"
%[2] Premble: It consists important Packages.
input{Chapters/Preamble}
makeindex
%[3] Begining our document. 
begin{document}
    pagenumbering{roman}
%[4] Titlpage
input{Chapters/Titlepage}
%[5] Acknowledgment
input{Chapters/Acknowledgement}
%[6] Abstract
input{Chapters/Abstract}
%[7] Declaration
input{Chapters/Declaration}
%[8] Nomenclature
printnomenclature[3cm]
%[9] Table of contents
tableofcontents
addcontentsline{toc}{chapter}{Table of Contents}
listoffigures
clearpage
listoftables
clearpage
pagestyle{fancy}

I configure makeindex with makeindex %.nlo -s nomencl.ist -o %.nls

I compile this way:

PDFlatex
makeindex
pdflatex
view

Does anyone know how to solve this , where am I missing anything? Sorry for the long question.
