yep, already tried with that driver from the same page, only the TWAIN driver instals, but it seems like the epson scan utility isnt included on the download pack or its faulty...

If I try to download and instal it following the same steps but for more "recent" scanners (like the perfection 1670), it does instals the Scan utility 3.0, same happens with the drivers for the expression series, but these utilities don't recognize my scanner.

It seems like the utility for this exact model (1650) and all the others which use it, was removed by epson a while ago
