I am using Delphi XE and have newly installed ImageEn 4.3.0 (after removing the previous version which I had not used very much)
When I try to compile any of the demo projects I always get the following error message:
[DCC Fataler Fehler] iexShellThumbnails.pas(301): F2039 Ausgabedatei 'C:\Program Files (x86)\ImageEn\DelphiXE\iexShellThumbnails.dcu' kann nicht erstellt werden
If you are running on Vista, Windows 7 or Windows 8 your projects can not be located in 'C:\Program Files (x86) because of UAC problems.
I generally place all my controls in C:\Controls and place all my projects in C:\Projects.
Try moving your project to C:\Projects\IEXShellThumbnails, open the project from that folder and try to compile. For example, each project should have its own folder with C:\Projects as the parent folder.
If it still does not compile, uninstall ImageEn and reinstall ImageEn at C:\Components\ImageEn for example.
