If you are using D2007 then you need to use the DCU's for the D2007 version and not the D2006 version.  That could explain the reason for your error message.

I just installed quick PDF v11 against D2007. 

I had an already existing project, and changed what was needed to get all to compile

Except:

[DCC Error] uPDFGeneratorController.pas(23): F2051 Unit DebenuPDFLibrary1112 was compiled with a different version of Classes.TStream

I admit have: 

1) CodeGear™ Delphi® 2007 for Win32®  Version 11.0.2902.10471 

(i am not sure if it is D2007 R2 or not) 

2) I am using a trial version of Quick PDF, so I am using DCU's from D2006

- this really does not sound good to me, classes.pas changes normally with every update/version

3) I do not know if I have installed all Delphi 2007 updates and if the D2006 DCU's will work anymore

My Delphi has the "December 2007 Update" installed and I do not recall installing that two weeks ago. 

I suspect therefore I have a D2007 R2 install. 

4) I have the following products installed. 

IDE Fix Pack 2007 4.3

HTMLTidy copyright (c) 1998-2003 (W3C) MIT, INRIA, Keio University

CodeGear Quality Insite™ 

Borland® Together® 

for example D2007 no updates, with updates.. and so on. 

This will all be useful so I can ask the man who looks after our Delphi installs. 

Thanks in advance

by the way:

The reason for the evaluation is that we have quickPDF 7.24 

No one noticed at first that  SetFormFieldValueByTitle resolves to some code that translates code pages incorrectly. I can re-write the code, but we have a standards board that says 3rd party code should be unaltered.
