how to configure vs2010 build to work

[graemeNPS]

my workflow uses dlls built with visual studio 2010.
I need the latest imagemagick to get the ability to turn off auto grayscaling (see my other topic:rgb converted to grayscale by imagemagick )
The dll's I build to use the imagemagick do not work with the latest window 6.9.3 installer, which I guess in a VS 2013 or 2015 build.

I have built IM 6.9.3.1 from source using visual studio 2010. the basic conversion of a tiff to jpg using a convert command works.
But, I have problems trying to convert e.g. a dng to a jpg. I assume it is a registry/configuration problem.
I have copied all the exe and dlls from the build to:
C:\telescope\IMBin
I have added C:\telescope\IMBin to the PATH variable.
version of convert works:
C:\TeleScope>convert -version

but the modules are not found for the dng conversion:

C:\TeleScope>convert c:\windows\temp\NPS_DNGCopy4696_26280.dng foo.jpg

more details: seems to work as a command line calling convert but not from the MagickCore::ConvertImageCommand API

I have compiled 6.9.3.1 in visual studio 2010, copied all the VisualMagick/bin files to c:\telescope\IMBin
I have path set to c:\Telescope\IMBin

// we use image magick thus to convert a file, with the logged command line:
..begin code snippet
//setup ImageMagick for a conversion...

MagickCore::ImageInfo *image_info;
MagickBooleanType status;
Magick::InitializeMagick(*argvnps);

MagickCore::ExceptionInfo* pMCException;
pMCException = MagickCore::AcquireExceptionInfo();

image_info=MagickCore::CloneImageInfo((MagickCore::ImageInfo *) NULL);

status= MagickCore::ConvertImageCommand(image_info, argc, argvnps, (char **) NULL, pMCException);
..end code snippet


this is the command we are passing to ConvertImageCommand(....), but it does not work, the output file is not generated:

//as a command line in Telescope directory, works fine:
