I'm trying to connect to Hp scanject pro 2500 f1 scanner but it is only recognized when using the library in 32 bit (when using the sample) but in 64 bit , it doesn't show the scanner and only shows the twain virtual scanner.

32bit apps can use 32bit twain drivers only. 64bit apps can use 64bit twain drivers only.

If your device's twain driver is 32bit, you can't use it from your 64bit application.
