I'm using the ImageMagickObject in a VB.NET 2005 application. I've got the follwing function to convert a file to jpg:

    Public Sub SaveJpeg()
        Dim MagImg As New ImageMagickObject.MagickImage
        Dim Files(1) As Object

        Try
            Files(0) = SourceFile
            Files(1) = DestFile
            MagImg.Convert(Files)
        Catch ex As Exception
            Dim ErrMsg As String
            ErrMsg = "Could not save JPEG file: " & ex.Message & vbNewLine & vbNewLine & _
                "Source File: " & SourceFile & vbNewLine & _
                "Destination File: " & DestFile
            MsgBox(ErrMsg, MsgBoxStyle.Critical)
            RaiseEvent ThreadComplete(False)
            Exit Sub
        End Try
        RaiseEvent ThreadComplete(True)
    End Sub

It works fine on my development machine. When I create an msi installer, I get an error when running it on another machine. The ex.Message portion of the error is this:

convert: 410: MissingAnImageFilename '(path to destination file)': unknown

I'm assuming I'm missing something in my installer. I've packaged all the DLLs included in the ImageMagick Program Files folder and put them in the system folder during the install. Yet something is still lacking because, if I run the ImageMagick installer on the computer with the problems, the conversion works.

Help please!
