edtFTPNet/Pro - License wording when distributing

Question

We have a C#.NET product which we distribute the edtFTPnetPRO.dll file.  We are just updating from a 9.0 version to 11.1.1.0.

What wording should be included in our installer's license screen to reflect the use of this product?
What files should be distributed with the software?

I have examined the license agreement page in the Help.  It mentions a license.txt file and talks about some specific wording that should be included.  I also found a copyright.txt which says it should be distributed along with the software.

Currently, I have something like this:

A portion of this software, the library, edtFTPnet.dll, is licensed under the Lesser GNU Public License (LGPL) from Enterprise Distributed Technologies Pty Ltd.  It is used without modification under this license.  To view more information about the LGPL or about this library, go to the web site: http://www.enterprisedt.com/products/edtftpnet/overview.html.  The provider of this library requires the following disclaimer:

Furthermore, the following copyright notices also apply to this file:

And plan to include the copyright.txt file 

Comments

It's a bit unclear here whether you are referring to edtFTPnet.dll (open source) or edtFTPnetPRO.dll (not open source). Can you clarify?

edtFTPNetPRO.dll

Having reviewed: https://enterprisedt.com/products/edtftpnetpro/doc/manual/html/licenseagreement.html again, I've removed the Lesser GNU Public License reference entirely

In the software's About dialog and installer's license dialog, I've kept the copyright messages (with hyperlinks) per section 6.1 of the license agreement webpage and a reference to a file called copyright.txt that was installed along with edtFTPNetPro.  I couldn't find the license.txt file mentioned in section 6.2.

The copyright messages follow a link to my company's EULA.

Further to that, the same copyright messages and the disclaimer in section 6.9 of the license web page will be included in the software's manual.

Thanks, that's all that is required (the Pro DLL is not GNU). license.txt == copyright.txt, will get that fixed.
