We have installed IEvolution2 4.3.0.0 on windows 7 pro sp1 64 bit
where we have a scanner Kodak i30 with a Twain driver installed and working,
in our application we get the list of scanners with: IEvolution.IEMulti.ImageList.TWainParams.Sources
this works well on 32 bit systems but it doesn't work on 64 bit, and we can't use the scanner in the application.
There are other methods to get the scanners that work on 64 bit?

Hello,
in my tests on a 64 bit system Sources returns the list of available devices.
Note that IEvolution 4.3.0 on a 64 bit system is actually a 64 bit application, so it should see only scanners having 64 bit drivers.

Hello, probably you are right, the driver of the scanner Kodak is the same for 32 and 64 bit and IEvolution 4.3.0 on 64 bit system don't see this driver because is not a 64 bit driver.
Do you think is possible in the future that IEvolution 4.3.0 on 64 bit could detect also these drivers?

I think no. Because 64 bit applications only sees 64 bit libraries. You should get the same behavior on other 64 bit apps.

You should use WIA instead of Twain. For 64bit support on Windows, manufacturers usually include a "WIA over Twain" driver.
