GdPicture Imaging

[PatrickE]

I have written a VB.NET 2008 application with one GDViewer control. works brilliantly. BUT.... when I try to deploy the application to a Dell Embedded Windows XP thin client, the installation fails before the app starts with the message system.invalidoperationexception. If I strip out all reference to the GDViewer4, then the application runs fine.
Can anyone help please?
Thanks in advance
