I just purchased and installed ImageEn 4.1.0 on Delphi 2006. I tried a little test program with a TImageEnView component, and it gives the following exception when running it:
"Project Project1.exe raised exception class EReadError with message 'Property EnableInteractionHints does not exist'."
You can duplicate this simply by creating a new VCL application, drop a TImageEnView component on the form and run it.
