on execution of function SHFileOperation with this path it results in returning of value 2. Which is error file not found.
After that I hard code the path to
"D:\\SVN_NEW\\NewProject\\setup files\\setup.exe"
Which is working fine.
Now, the question is \\..\\ Is it giving problem. What should I do to change my directory to second one. As this is working fine and this is what I really need.
