Invalid Width/Height when making a thumbnail

The following code used to work when I was using the free evaluation version EVAL 14.5.  Upon purchase and installing the software version 14.5, I am now recieving "Invalid Width/Height"  error.  Any ideas?

 

OS is Win2000, language is C#, .Net Framework v1.1.4322,

 

byte[] photo;

RasterCodecs.CodecsPath = @"C:\\Program Files\\LEAD Technologies, Inc\\LEADTOOLS 14.5\\Bin\\Dotnet\\v11";

RasterCodecs codecs = new RasterCodecs();

codecs.Options.Jpeg.Save.QualityFactor = 50; // Range from 2 best qual & largest to 255.

Leadtools.Codecs.CodecsThumbnailOptions options = new CodecsThumbnailOptions();

options.Height = 192;

options.Width = 256;

IRasterImage ri = codecs.ReadThumbnail (imagePath, options, 1)

Actually the code posted is creating the error "Invalid File Format" since the CodecsPath is pointing to the new installation path.  The old path generated the "Invalid Width/Height" error.

 

Art,
Does this happen with a certain file or group of files, or with any type of file? If it's a specific file or group, send me the file and tell me which (build) version of LEADTOOLS you are using.
If your build is older than 14.5.0.10, please download and apply the latest patches from our support site and try with them.
If you want to send files, you can either post them here or email them to support@leadtools.com. If you post or email files, please put them in a ZIP file first.

I resolved problem.  I uninstalled both versions (EVAL and latest) and reinstalled ensuring only current DLLs remained.  Apparently, some old DLLs were getting in the mix.  All is well now.
