I have customer PC that owns an old HP Scanjet 5530. I have been able to install the driver in Windows 7 (it's necessary to use the Vista drivers in compatibility mode). If i use the HP utility (Photosmart essential) i'm able to aquire images. If i use my Delphi program (compiled with imagen 5.2) i have an error when i try to aquire. The error seems to say that the automatic feeder is not loaded. This accessory is not present in the scanner. I have tried to download a demo app (http://www.imageen.com/cgi-bin/dlredirect.asp?demo=run/FullApps/PhotoEn3/ImageEx.exe) and i have the same error. I guess the demo is compiled with latest imagen version...
