problem with vc6 project in VSExpress (CVT1100: duplicate resource

[martin]

I've just been handed an old project (written in VC6 or possibly an earlier
version) which I need to compile in Visual Studio Express. I went through the
normal solution coversion process but the code unfortunately does not
compile. There seem to be a problem with the resource but the error message
is very vague so I don't know which part (configuration or code) that needs
to be modified. I think the relevant error is this one:

CVTRES : fatal error CVT1100: duplicate resource. type:MANIFEST, name:1,
language:0x0409

I have no idea on what this error means or where I should continue my
investigation? Things I have noted so far is:

- The original project contains a file named Blah.exe.manifest (even though
I don't know what this file is for)
- Under Project Options :: Linker I have found that VSExpress has an option
to "generate manifest". This option is TRUE but turning it off does not help
afaik.

The complete build log error is included below:

1>Linking...
1> Creating library Debug/Blah.lib and object Debug/Blah.exp
1>CVTRES : fatal error CVT1100: duplicate resource. type:MANIFEST, name:1,
