Hello Farrukh,
Thanks for letting me know the attached was not included. The WIX markup is included below. The error is generated for duplicate source code filenames, even though the directory paths are different.

I didn't find the zip file. However from log, it seems that you have added some files more than one times using same Component IDs (or may be File Ids). For example, main.cpp's Component at line 41 is also present at line 61. Please check Component definition where it says "Location of symbol related to previous error.".
Can you please share only Product.wxs?

I have not been able to resolve a "error LGHT0091: Duplicate symbol" error
message that has been plaguing me for 2 days and I am hoping to find some
help here.
The attached ZIP file contains a small Visual Studio 2010 solution which can
be used to replicate the problem. The sample VS2010 solution includes two
C++ projects and a WIX installer. The two C++ projects contain
identically named source files (e.g. main.cpp, main.h, stdafx.cpp,
stdafx.h). Attempting to build a WIX project with non-unique source code
filenames (i.e. their filepaths differ but the filenames are the same)
generates error messages similar to 'error LGHT0091: Duplicate symbol
found'. The complete error message generated for the sample solution is
included at the end of this email message. Google lists only handful of
posts which cite the LGHT0091 and LGHT0092 error numbers and these refer to
GUI related problems - something my WIX installer avoids.
One solution is to provide unique source code filenames between projects -
but this is a very impractical, particularly for files with common Visual
Studio generated filenames names such as 'stdafx.cpp', 'stdafx.h',
'resource.h', etc.
So my question is has anyone encountered the problem before and found a
solution? I would appreciate any suggestions you might have.
ThanX
Ian
