Re: visualstudio installer dependency problem

I created a C# web service that converts a PDF to TIFF images, and use VisualStudio's installer to create a corresponding msi file.  Everything works fine when I install this onto a development machine but when I try installing to a production machine things error out.  Everything points to missing dependencies but I can't figure out which are missing, much less if this is really the problem. When I try loading the PDF using this method:

Leadtools.Codecs.RasterCodecs.Load( System.String fileName , System.Int32 width , System.Int32 height , System.Int32 bitsPerPixel , Leadtools.RasterSizeFlags flags , Leadtools.Codecs.CodecsLoadByteOrder order , System.Int32 firstPage , System.Int32 lastPage )

Here's the error logged:

Leadtools.RasterException: Either the files required for initializing the PDF engine were not found or they were found but they are incorrect
   at Leadtools.RasterException.CheckErrorCode(Int32 code)
   at Leadtools.Codecs.RasterCodecs.Load(LoadParams loadParams)
   at Leadtools.Codecs.RasterCodecs.Load(String fileName, Int32 bitsPerPixel, CodecsLoadByteOrder order, Int32 firstPage, Int32 lastPage)
   at USHH.MLS.PDF2OneNote.PDF2OneNoteLib.ConvertPDF2OneNoteTIFF(String pdf, String onenote, String sectionName, String author)

Here are the dlls that are present in the same directory as the custom dll that attempts to use them:

The development machines (WinXP) have the following installed on them, while the production machine (Win2K) does not:

Any assistance is greatly appreciated.  Thank you in advance.
