If you obtained a royalty-free LEADTOOLS product, simply distribute the Leadtools.dll from the \Redist\NoNag\Dotnet directory.
If you obtained a royalty LEADTOOLS product (Document/Medical), then you will see a nag message when you run your application. The Leadtools.dll that was installed into your \Bin directory produces this message. This Leadtools.dll has the Document/Medical features unlocked for you. In order to remove the nag message, you must contact LEAD Technologies to obtain "keys" to unlock the specialized features in the "no-nag" DLL, which is located in the\Redist\NoNag\Dotnet directory. When you distribute your application, you must distribute the DLL from the \Redist\NoNag\Dotnet directory, and must unlock the specialized features in your application.
Note: There is also a nag / eval version of Leadtools.Windows.Controls.dll. This version will place a 'watermark' on all displayed images. When you distribute your application, you must distribute the DLL from the \Redist\NoNag\ directory.
