how do i open the twain source on my canon lide 60 scanner

I downloaded and installed the drivers for the lide 60, told the computer to manually find the lide 60 drivers for my scanner, and installed the canoscan toolbox for vista 64 bit. I have an lide 35, and there are no 64 bit drivers for it. But you (and the Paint.NET developers) should be aware that these limitations essentially make the program useless to people for whom scanning is important. Im not sure if this will work on the lide 20. I don't know about the built-in interface. I understand that there's nothing you can do about document feeder support due to the way Paint.NET forces you to interface with it. From my point of view those are all utterly basic features, and a program that lacks any of them is simply not adequate for my needs. Its built-in scanner interface doesn't let me adjust contrast, brightness, or resolution Twainable doesn't support the document feeder. I thought Paint.NET would be it, but it won't. That started my search for a new image processing program. Windows 7 won't run my old version of PSP, and I found the current version to be a huge, complex thing in which everything is possible and nothing is easy. I used to use Paint Shop Pro as an image processing program, mainly for scanning documents and doing simple cleanup operations (flood fill of dirty backgrounds, etc). Twainable won't be useful to me with that limitation. There's nothing more to be done here, but in return for responding to my questions, I think you deserve feedback.
