windbg symbol files unable to resolve

My executable is setup.exe, I have a pdb file named setup.pdb in the same directory c:\ade\bpurana\.ade\view_storage\bpurana_oui_424\oui\cd\disk1

My symbol file path is this

cache*c:\symbols;srv*https://msdl.microsoft.com/download/symbols;c:\ade\bpurana\.ade\view_storage\bpurana_oui_424\oui\cd\disk1

When I reload using this 

.reload /f

I can see this error :

SYMSRV:  c:\symbols\image00000001`3f6b0000.dbg\574587D664000\image00000001`3f6b0000.dbg not found

*** ERROR: Module load completed but symbols could not be loaded for image00000001`3f6b0000

I am wondering

  1. why is it looking for a dbg file when the pdb is already present in the path.
  2. Why is there a refernce to the image00000001`3f6b0000.pdb ; when the setup.pdb is in the symbol path?
  3. Where is this image<> file name being populated from ?

Edit 1:

Command used for compilation :

    icl.exe /nologo /MTd /W3 /Gm /GX /Zi /Od /D "WIN64" /D "_DEBUG" /D   "_WINDOWS" /Fp".\win64\debug\setup.pch" /YX /Fo".\win64\debug\\" /Fd".\win64\debug\\" /c ..\c\runInstaller.c

Edit 2 :

This is what I see when I try the cdb on the exe file. It seems to have a image<> executable within .

 C:\Program Files\Debugging Tools for Windows (x64)>cdb.exe -c "q" C:\ADE\bpurana_oui_win\oui\cd\Disk1\install\setup.exe  | grep -A 1 -i Execu*
 Executable search path is:
 ModLoad: 00007ff7`e4e10000 00007ff7`e4e74000   image00007ff7`e4e10000

The ICL version is this :

[C:\ADE\bpurana_oui_win\oui]icl /version
Intel(R) C++ Intel(R) 64 Compiler XE for applications running on Intel(R) 64, Version 14.0.4.237 Build 20140805

Even with this the issue is still persisting is there anything else I need to fix ?
