My RX600 lost it's 35mm slide scanning ability last month due to a Win7Pro restore. I eventually dug up a TWAIN from a US Epson website and installed it and it works to a degree but am advised it is unstable. Epson11541 7564kb. Input dialogue allows it to be run in a variety of compatibility modes according to your system. Could be your answer too? Am Googling for others that might be better but the same one comes up. Might be your answer too.
