Thank you so much for the reply.
I tried to install and unistall OCR component before and after installing Epson Scan but nothing change.
During the OCR component installing everything seems ok (installation complete without warning) but I can't see anything that proves that something has been installed (no icon, no any folder with ocr label) even if the Epson Scan OCR Component is listed as installed in the Control Panel-> Programs.
In any case is there an order of installation? Should be installed Epson Scan before the Ocr component? Is there any way to set some option in Epson Scan to force using Ocr component?
