When I try to load a pdf image using the code below I get the following:

"Leadtools.RasterException: Either the files required for initializing the PDF engine were not found or they were found but they are incorrect"

This same code works on other machines, so I think that it is a dll version problem. I checked the paths that are specified in the code and they exist. All of the dll versions seem to be correct as well. Any ideas? Could it be a problem with the GS_LIB key in the registry pointing to different files or something (even though it is pointing to the same version of the files in my case)?

Code below:

 Public Shared Sub ConvertImage(ByVal SourceFileName As String, ByVal TargetFileName As String, ByVal ImageFormat As Leadtools.RasterImageFormat, ByVal bitsPerPixel As Integer)

        Dim mCodecs As RasterCodecs = New RasterCodecs
        Dim image As IRasterImage


        mCodecs.CodecsPath = CodecsPath
        mCodecs.Options.Pdf.InitialPath = PDFEnginePath

        mCodecs.Options.Pdf.Load.XResolution = 300
        mCodecs.Options.Pdf.Load.YResolution = 300

        mCodecs.Options.Load.XResolution = 300
        mCodecs.Options.Load.YResolution = 300

        'MsgBox("about to load image")

            MsgBox("about to load image")
            image = mCodecs.Load(SourceFileName.Trim)
            MsgBox("loaded image")
            'image = mCodecs.Load(SourceFileName, bitsperpixel, CodecsLoadByteOrder.RgbOrGray, 1,
            'mCodecs.Save(image, TargetFileName.Trim, ImageFormat, bitsPerPixel)
            'MsgBox("about to save")
            mCodecs.Save(image, TargetFileName.Trim, ImageFormat, bitsPerPixel, 1, image.PageCount, 1, CodecsSavePageMode.Overwrite)
        Catch ex As Exception
            MsgBox(ex.ToString & vbCrLf & ex.Message)
            If Not image Is Nothing Then
            End If
        End Try

    End Sub

In addition to the files from LEADTOOLS14.5\Redist\PDF, you also need Leadtools.Pdf.dll and Leadtools.Codecs.Pdf.dll

Are you sure all these files are identical on both the PC that works and the PC that fails?

Also, are you sure the value of PDFEnginePath is set correctly?

The path to the PDF Engine files is correct. However, I did not have the leadtools.pdf.dll file in my codecs directory. I am going to try again with this in the codecs dir to see if this resolves the issue.
