Hi Twain Expert,
We are using the twain_32.dll(1.9)
Our App is 32 bit application. In Win 32 it is working fine. But in Win7 64 bit ,We are not getting the MSG_XFERREADY Message.
The scanner start ,pages are scanned and after the scan is complete MSG_XFERREADY is not fired.
The scanner source is installing TWAINDSM.dll and its own datasource. It is working fine in 32 bit machine.But in 64 bit machine we are not getting MSG_XFERREADY.
We have in our machine TWAINDSM.dll as well as twain_32.dll
Please let me know your inputs.
