I have Epson Scanner Perfection 3170. I have downloaded twain driver and Epson Scan Utility v265A. I can't open it with the message Epson Scan cannot be started. I want to solve the start up problems for Epson Scan. The instruction said to close Epson scan server. My problem is I don't have Epson Scan Server to close. Therefore, it's not open, so what do I need to do?
